摘　　要：为解决某种对抗态势下箔条与目标飞机多普勒频率相差过大导致箔条干扰PD雷达导引头效能降低的问题,采用了有源无源协同干扰方式,使箔条云具有与目标飞机相似的多普勒频率。基于有源无源协同干扰机理,对有源照射信号调制频率影响因子进行研究,给出导弹不同攻击态势下有源照射信号频率调制规律。In order to solve the problem that the efficiency of chaff jamming pulse Doppler(PD)radar seeker is reduced due to the excessive Doppler frequency difference between chaff and target aircraft under some countermeasure situations,active and passive cooperative jamming mode is adopted to make chaff cloud have Doppler frequency characteristics similar to that of the target aircraft.Based on the principle of active and passive cooperative jamming,the influence factors of active irradiation signal modulation frequency are researched to give the frequency modulation law of the signal under different attack situations of missiles.
