In order to solve the degeneracy of the jamming ability of chaff cloud, a compound jamming method is proposed. The jamming process is as follows: The signal of enemy airborne fire control radar or air missiles seeker is received by airborne electronic jamming equipment, and then the signal is irradiated on chaff cloud by airborne complexity launching antenna. The jammed signal is reflected by chaff cloud, which will be received by enemy radar , forming a false target, and this false target is different from the false target formed by the irradiation on chaff cloud of radar signal. The simulation results show that using this compound scheme the scatter area of chaff cloud received by enemy is enlarged by even hundreds of times compared with the original one, enhances blanketed ratio. So the spread time of chaff cloud is shortened and the feasibility of this method is validated. The comprehensive jamming ability of aircraft is boosted by using the compound jamming method. Therefore, the method, to some extent , is of a stronger practical value.%针对箔条自卫干扰对新体制雷达的干扰能力和效果不断下降的问题,提出了一种复合干扰方法.该方法运用机载电子干扰设备接收并转发敌机载火控雷达或空空导弹制导导引头(以下简称敌方雷达)发射的信号,经由载机的干扰发射天线照射到箔条云上,箔条云对干扰信号二次辐射,被敌方雷达接收,形成假目标(不同于箔条云反射雷达信号形成的假目标),起到诱骗干扰作用.仿真计算结果表明:采用此复合干扰后,敌方雷达接收到的箔条云有效反射面积比原来提高几十倍甚至几百倍以上,从而缩短了箔条云的展开时间,增大了压制比,并验证了此方法的可行性,提高了飞机的综合干扰能力,具有较强的实用价值.
