摘　　要：投放箔条弹是飞机受到主动雷达制导导弹攻击时一种重要自卫手段,对于保护飞机免遭空空导弹攻击具有重要意义。基于干扰过程中主动雷达多普勒导引头信号处理的波形特性分析研究了这一问题。建立了箔条弹干扰主动雷达导引头模型并对模型特性进行了分析,研究了箔条弹打出后主动雷达导引头信号处理各个阶段的波形特性。最后从信号级的仿真角度通过对波形特性对比分析指出了箔条弹干扰主动雷达多普勒导引头的干扰效果。As an important method to protect airplane when the airplane is locked on by active Doppler radar seeker, throwing chaff cartridge plays a significant role. The model of chaff cartridge jamming active Doppler radar seeker was built and the model character was analyzed, the wave character for active pulse Doppler radar seeker processing signal during different stage was researched. From the angle of signal level simulation, the impact of chaff cartridge on jamming active Doppler radar seeker was discussed by contrasting the wave character.
