摘　　要：研究部分极化干扰条件下极化阵列的滤波抗干扰性能,期望信号为完全极化波,干扰信号为部分极化波。利用最大信噪比准则得到阵列最大输出信号干扰噪声比(SINR)的解析表达式,分析干扰极化度,到达角等因素对阵列抗干扰性能的影响,仿真实验验证理论分析的正确性。Filtering anti-jamming performance of polarized array is studied theoretically under partially polarized situation. It is expected that signal should be completely polarized wave and interferences should be partially polarized wave. Analytic expression of signal to interference plus noise ratio （SINR） of maximum output signal of array is derived as per maximum signal-to-noise ratio （S/N） criteria; and many fac tors such as polarization degree and direction of arrival （DOA） of interference signal which would affect anti-jamming performance of array are analyzed; correctness of theoretical analysis is verified by simulation test.
