摘　　要：推导了受干扰目标的极化协方差矩阵及其统计特性,建立了干扰条件下最优极化检测器的数学模型,在此基础上以水面舰船和装甲车辆为例分析了不同干扰功率与干扰机极化配置方式对极化雷达目标检测性能力的影响,揭示了利用压制性干扰降低极化雷达目标检测性能的最佳干扰功率需求。Firstly the polarimetric covariance matrix and the statistical properties of the target which has been interferenced is derived, the mathematical model for optimal polarization detec-tor under interference conditions is established, then to take surface ships and armored vehicles for example to analyze the effect of different interference power and jammer polarization configu-rations on polarimetric radar target detection capabilities, revealing the optimal jamming power demand which make use of repressive jamming to reduce polarimetric radar target detection per-formance.
