Airliner Self Protection
l On-Board (DIRCM)– Modulation’s Success
Depends on Threat’sTracking Technique
– Requires ThreatAnalysis Capabilities
l Defeat of AdvancedTrackers May Be
Difficult if DIRCMPower Is Not Sufficientto Cause Damage
l Off-Board (Flares)– Deployment Sequence
Relative to End Game(Timing) Is Important
For Success– Success Is Engagement
Geometry Dependent
l Success Is Relatively
