摘　　要：在无源干扰中,箔条云因其具有全频段、干扰能力强等特点而被广泛采用。空中目标发射箔条弹对舰空导弹武器系统跟踪制导雷达影响非常严重。首先分析了箔条云散射原理,研究了基于舰载雷达照射的箔条云散射功率数学模型,该模型考虑了不同体积单元回波起伏,给出箔条云散射功率的直观计算方法,将该模型转化为雷达径向上随机积分形式。最后,通过仿真分析,给出了不同距离段箔条云散射功率变化情况,并与点目标散射功率进行了对比,阐明了箔条云散射功率的变化规律,为分析箔条云的散射特性提供了简便可行的方法。Chaff cloud has the characteristics of the whole frequency and effectiveness in passive jamming.Chaff rocket emitted from aerial carrier has bad effect on tracking-and-guiding radar of ship-to-air missile weapon system.Firstly,the chaff cloud scattering theory is analyzed.And then the stochastic integral maths model of chaff cloud power is advanced considered of different volume echo amplitude fluctuating,the range profile integral maths model is advanced for convenience analyzing.The result shows the maths model can be correctly used to calculate the chaff cloud echo power for estimating its scatter characteristics.
