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，对极化雷达的电子干扰与反干扰具有重要的理论意义。The polarimetric covariance matrix and its statistics property are deduced under electronic jamming in the paper. Then, the mathematic model of optimum polarimetric detection is established for jammed radar. Exampled as ships and vehicles, the influence of jamming power and polarization configuration on performance of polarimetric radar is analyzed. The optimum power requirements to degrade the target detection performance of polarimetric radar by using suppressing jamming are made clear. This work is important for ECM and ECCM of polarimetric radar.
