Active jamming of an infrared seeker with amplitude modulation reticle

For the purpose of jamming the amplitude modulation reticle system,two methods of active jamming of infrared seeker are analyzed by using numerical simulation based on the operation principle of an infrared seeker with amplitude modulation reticle.The results show that the jamming source with a slow variation of amplitude will warp the target's azimuth received by the seeker.But it can not make the target escape from the scout of the seeker.At a repetition rate nearly equal to the carrier frequency of the reticle system,the jamming source will disturb the target's signal received by the seeker,and make the seeker lose the target.If the intensity of the jamming source nearly equals to that of target's radiation,the jamming can be achieved.
