Latest MSPP Version (3)Latest MSPP Version (3)
• Analyst Plus (A+) Tool Set Features:– Editable Environments– Expanded CG Sensor Library– Expanded Target Set– New Classification and Evaluation Prediction
Modes (in addition to Detection)– New Batch Processing Mode – Significantly Reduced Run Times
MSPP Main Graphical User Interface
Platform: Air (altitude: 500ft)Sensor: OldIR and NewIRTarget: 6-Person Raft with 2 PeopleEnvironment: Cape Cod August, 11pm local time
MSPP Sample Output
These results indicate that in both NFOV and WFOV, OldIR provides moderately better detection results than NewIR.

These azimuthal plots use color to POD at increasing ranges from the center where the sensor is positioned. As in the previous slide, these results indicate that in both NFOV and WFOV, OldIR provides moderately better detection results than NewIR.

FY05 MSPP TasksFY05 MSPP Tasks
• Modify MSPP for unrestricted operation– implement the same approach used by TAWS
• Incorporate radar wind-dependent sea clutter model (AREPS)
• Investigate requirements to interface/integrate MSPP with
mapping software such as ESRI’s Arc View
• Add graphical output to batch mode (currently tabular)
• Validation of method used to estimate minimum detectable temperature (MDT) data for IR predictions
• Expansion of MSPP Prediction Capabilities– Addition of CCD TV model (planned FY06)– Visibility impact on IR/NVG predictions (planned FY06)– Account for target height in IR/NVG max range
predictions– Modeling of retro reflective effects for NVG– Modeling of unaided visual detection– Effects of radar scan-to-scan integration
