Infrared jammer source is intended for active protection of helicopters against guided missiles with IR homing devices. The majority of such known stations are intended for suppression of IR homing heads with amplitude-phase modulation. Its interfering signal is surfeit 1.5 to 2 times to the signals emitting from the helicopter’s engines, and on occasion up to 20 times. The system is capable of suppressing IR homing heads with heightened noise immunity for other types of modulation like frequency-phase. This paper describes a design and simulation method to assess the effectiveness of IR seeking missile in presence of IR jammer sources on a developed program by paper authors. Proposed method models IR jammer for the missile aerodynamics in six degree of freedom, the missile guidance, and control system. Method validity is verified with experiments on IR seeker reticle. The simulations results show that the proposed design can disturbance tracking and guidance loops adversely. Also, it can increase miss distance.
