有源干扰和无源干扰结合使用形成复合干扰，就是通过有源干扰照射箔条云后，箔条云能影响制导雷达导引头的干扰方程，使其检测范围减小了2—2．5dB（m）；同时，复合干扰能够增大干扰信号进入导弹导引头的入射角，使得有源干扰飞机的速度方向与导弹连线方向基本一致即可使复合干扰信号进入导引头的速度门，增大了有源于扰和箔条干扰的有效干扰范围，从而实现对制导雷达的干扰。

Passive jamming integrated with active jamming forms integrated jamming.That means using active jamming to illuminate the chaff cloud,so as to change the jamming equation for homing head of guidance radar and the detection range will be reduced by 2~2.5 dB(m).Meanwhile,integrated jamming could enlarge the incidence angle of jamming signals radiated into missile homing head,and expand the effective jamming range of active jamming and chaff jamming.Therefore,the jamming against the guidance radar is realized.
