Algorithm of aircraft hit probability in infrared jamming scenario

In an encounter between an aircraft and a missile equipped with an IR seeker,scenario of the terminal phase(endgame) is an important phase in aircraft susceptibility evaluation.Electronic countermeasure(ECM) is a self-protecting measure for the aircraft in this scenario,and infrared bait is always used for jamming the missile with IR seeker,which takes the target as an infrared radiation point.Algorithm of aircraft hit probability in multi-infrared bait jamming scenario is addressed in paper.We assume that the aircraft infrared radiation intensity is a function of azimuth angle,and the launching time of multi-infrared bait obeys probability distribution.Based on such assumption,a dynamic model of aircraft-bait-missile is founded,and finally we get simulation value of hit probability.
