摘　　要：箔条干扰是最为常用的无源干扰方式之一,主要依靠其电磁散射特性实现对雷达接收机的干扰。对箔条散射雷达截面进行研究,利用非相干模型推导了不同入射极化条件下单根箔条平均雷达截面,得到了箔条极化散射矩阵,并对单根箔条极化散射特性进行分析。提出了相干条件下的理想摆放模型,得到了更贴近实际使用的单根箔条平均雷达截面数值,为充分发挥箔条无源干扰效能打下基础。Chaff jamming is one of the most commonly used passive jamming methods,and mainly depends on its electromagnetic scattering characteristics to jam radar receivers.In this paper,the radar cross section(RCS)of chaff scattering is studied,and the average RCS of a single chaff under different incident polarization conditions is derived by using incoherent model.The scattering matrix of chaff polarization is obtained,and the polarization scattering characteristics of single chaff are analyzed.An ideal placement model under coherent conditions is proposed,and the average RCS value of a single chaff is obtained,which is more close to the actual use,and lays a foundation for giving full play to the passive jamming efficiency of chaff.
