现有雷达目标鉴别方案大多是针对单极化假目标设计的，对于能够在极化域上模拟雷达目标特性的全极化转发式假目标难以凑效。分析了全极化转发式假目标的特性及其与真实雷达目标的差异，定义了雷达目标之间的极化特征描述子矢量相似系数，以共交极化比和极化特征描述子矢量相似系数为特征参量，设计了全极化假目标的极化鉴别方案。利用八种真实雷达目标实测数据仿真实验，表明了该极化鉴别方案的有效性。%There are many discrimination schemes designed for the single-polarization decoy. They are inefficient when turning to the full-polarization repeater decoy, which is similar to the real target of radars in polarization domain. Features of the decoy and its difference from real targets are analyzed. The matching coefficient between polarization characteristic vectors of two radar targets is defined and used to address further the distinction between the decoy and real targets. A polarization discrimination scheme of the decoy against real targets is designed by combining the co-polarization and cross - polarization ratio and the matching coefficient. Simulation experiment in terms of experimental data shows the decoy is identified with a high efficiency from real targets.
