摘　　要：从最一般的电磁波椭圆极化方程出发,分析了线极化波和圆极化波的构成条件、极化分解和极化的合成方式;探讨了箔条云的散射特性和极化特性;重点研究了箔条云与测试雷达之间的极化特性匹配关系对散射截面测量结果的影响.最后,指出了箔条云雷达截面测量方式对箔条工程实践的作用.Based on the ellipse equation of electromagnetic waves, the composing conditions of linear and circular polarization wave, the decompounded and compounded polarizations of electromagnetic waves are analyzed. The scattering characteristic and polarization characteristic of chaff clouds are discussed; the influences for RCS measurements relating with polarization matching between chaff clouds and measure radar are detail discussed. Finally the RCS measurement methods of chaff clouds for design, test and application of chaff engineering are important.
