摘　　要：研究了最优极化滤波问题,针对已有工作对信号干扰噪声比(SINR)极化滤波器性能分析的不完备性,对强干扰环境中SINR极化滤波器的性能进行了全面分析。推导出强干扰环境中SINR极化滤波器最优解的解析表达式,构建电磁环境参数空间来综合考虑不同电磁环境参数对滤波性能的影响,详细讨论了滤波性能对信号极化度、干扰极化度及极化匹配系数等参数的复杂依赖关系,最后给出性能分析的相关结论。The problem of optimal polarization filtering of signals is studied, and a comprehensive Analysis of the performance of Signal-to-Interference-and-Noise-Ratio （SINR） polarization filter in strong interference background is presented, which has not been considered deeply enough heretofore. The relation between the performance of the SINR polarization filter and the parameters of the electromagnetic environment is discussed with the building of Electromagnetic Environment Parameter Space, and some significant conclusions on the performance analysis are summarized.
