摘要
从一般的雷达截面积定义出发，文中给出了箔条云雷达截面积同偶极子雷达截面积之间的关系。对于单基地箔条的雷达截面积，分别就球面、水平面、球缺面和圆锥面均匀分布，推导了雷达截面积公式。对于双基地箔条的雷达截面积，本文利用近似公式，导出了与上述相同分布的箔条平均雷达截面积。对发射－接收各种极化组合的箔条雷达截面积，本文介绍了最近发表的几个有代表性的文献供读者参考。
Based on the definition of radar cross section,it is given the relationship between the cross section of a dipole and that of a chaff cloud.In detail,the backscatter cross sections of four kinds of distributions of chaff are discussed,the bistatic radar cross sections of a linear polarization field are found according to the approximation formula,and bistatic cross sections applicable to scat-tering from a chaff cloud randomly positioned and oriended are introduced.The chaff cloud can have an arbitrary location relative to an illuminant radar,and the antennas of transmitter and receiv-er can have an arbitrary specified polarization.
