Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

bull The biggest finding in this set of

different SLSS firing policy than
SSD SADM would shoot one
shot the first engagement and 2
shots for subsequent
engagements The SSD model
employed an adaptive algorithm
which would shoot 2 shots on

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

generate results with good
agreement after some
reconfiguration of their
reengagement parameters
bull Generally times for intercept
were within 2 seconds and
intercept ranges within 05

bull The biggest finding in this set of
data was that SADM had a
different SLSS firing policy than
SSD SADM would shoot one
shot the first engagement and 2
shots for subsequent
engagements The SSD model
employed an adaptive algorithm
which would shoot 2 shots on
the first round if it was the only
engagement opportunity

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

reconfiguration of their
reengagement parameters
bull Generally times for intercept
were within 2 seconds and
intercept ranges within 05

bull The biggest finding in this set of
data was that SADM had a
different SLSS firing policy than
SSD SADM would shoot one
shot the first engagement and 2
shots for subsequent
engagements The SSD model
employed an adaptive algorithm
which would shoot 2 shots on
the first round if it was the only
engagement opportunity

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

bull Generally times for intercept
were within 2 seconds and

bull The biggest finding in this set of
data was that SADM had a
different SLSS firing policy than
SSD SADM would shoot one
shot the first engagement and 2
shots for subsequent
engagements The SSD model
employed an adaptive algorithm
which would shoot 2 shots on
the first round if it was the only

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar
performance

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

Subsonic Threat Performance Active Missiles
bull Results showed excellent
agreement for subsonic
threats with active
missiles
bull Generally times for
intercept are within 2
seconds and intercept
ranges are within 02
nautical mile
bull Some of the initial
detection ranges were a
little further out for SSD
but that difference can be
attributed to the fact that
SSD assumes ldquoperfectrdquo
radar detection and SADM
models actual radar

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

SSDSADM Comparison
Fidelity Differences between Models Drive Data Requirements and Learning Curve
Criteria SSD SADM
Ease of use Easy to set up and use ndash low learning curve
Easy to set up exact conditions (detect launch
intercept etc) you wish to study
Significant learning curve for new users Large
set of default values available but analyst must
validate them for his study Requires many
more inputs to run a scenario
Execution Speed Runs fast and provides many Monte Carlo runs
to analyze in minutes
Runs fairly quickly though it can take hours to
complete large numbers of Monte Carlo runs
Modeling
approach
Uses look up tables to characterize most
performance Validity depends on source of
data excellent if from high fidelity sims
Uses physics based models more than look up
tables (models sensor detections flies missile
at physics level)
Sensor models Sensor models are very basic providing low
fidelity Analyst will use sensor as ldquoblack boxrdquo
using SSD
Sensor models are medium fidelity allowing an
analyst to configure a realistic sensor model for
their study with a sensor as key component
Weapon models Models exist for a large variety of weapons
and model can be readily adapted for new
weapon models using look up tables
Medium fidelity physics based models No
capability to model dual mode missiles like
RAM or future ESSM Block 2 today though in
development
Target audience Provides results tuned to missile analystrsquos
needs
Provide results tuned to ship system designerrsquos
needs with enhanced trade-offs for sensors
weapons and threats available Utilized in
Navy for hard kill soft kill interaction analysis

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis

bull Both models were able to
generate results with good
agreement after some
reconfiguration of their
reengagement parameters
bull Generally times for intercept
were within 2 seconds and
intercept ranges within 05
nautical mile
bull The biggest finding in this set of
data was that SADM had a
different SLSS firing policy than
SSD SADM would shoot one
shot the first engagement and 2
shots for subsequent
engagements The SSD model
employed an adaptive algorithm
which would shoot 2 shots on
the first round if it was the only
engagement opportunity

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to

SummaryConclusions
bull This study identified a strong correlation between fidelity data
requirements and learning curve for the models evaluated
bull Our initial results indicate that both SSD and SADM while similar
models in many ways provide unique capabilities
ndash SSD provides an important ldquoquick lookrdquo capability that is important early
in the lifecycle
ndash SADM provides a more ldquoin depthrdquo look at relationships between system
components that will increase in importance as the lifecycle advances
bull We are currently looking at a mixed use strategy where both SSD
and SADM will be used at different points in the system lifecycle to
support weapon system analysis
