| 摘 要： | 提出一种利用单脉冲跟踪雷达的和、差波束特性差异的极化估计算法。基于目标散射回波和固定转发式有源假目标干扰产生物理机理的差异,设计了极化相似测度、极化相关系数、极化欧式距离等干扰鉴别参量,提出了有源假目标干扰鉴别算法。该技术无需增加极化通道,降低了计算和处理难度,更易工程实现。仿真结果证明了该方法的有效性。

| Abstract: | A new polarization measurement algorithm by using the sum and difference beam differential property of mono-pulse radar is given.Based on the generation mechanism differences between target scattering and multi-false-target jamming,the polarization similarity measure,polarization correlation coefficient,polarization Euclidean distance is designed as discrimination parameter.The active-decoys jamming discrimination method is given.The novel method does not ask for adding polarization channel which reduced computation and processing difficulty,easy for engineering realization.The validity is proved by simulation. |
