摘要

<FONT face=Verdana>本文研究了箔条云散射的极化统计特性。首先，给出了感应电流的大小随入射角变化的更为精确的计算结果，得到了箔条的极化散射矩阵、RCS矩阵及二者的统计特性。然后，推导了箔条云回波的振幅、RCS和箔条云极化散射矢量的概率分布表达式，得到了箔条云同极化通道回波互相关系数为1/3，同极化和交叉极化通道之间不相关等一系列结论，为箔条云极化信息在干扰和抗干扰中的应用打下基础。

Abstract

Statistics characteristics of polarimetric scattering from chaff cloud is studied. At first

the more accurate calculation result is given

which tells how the current value varied with the direction of incident electromagnetic. On this basis

polarimetric scattering matrix and RCS matrix of chaff are presented

and their statistics chafteristics are studied. Then PDF function of chaff cloud’s altitude、RCS and polarimetric scattering vector are derived. A series of conclusions are draw at last

such as: the correlation coefficient between the two co-polarized channels is 1/3

the correlation between the co-polarized and cross-polarized channels is zero.
