摘要

为了有效的对被动雷达目标进行识别,提出利用极化方式差异性进行被动雷达目标识别的方法。分析了不同极化方式雷达波的表征方式,提出了变极化接收识别方法,利用虚拟变极化接收技术分析其瞬时极化方向并根据其一二阶差分特性进行极化方式判断。根据不同极化方式雷达波的时域特性,提出基于最小幅度输出准则和基于幅度比和相位差联合判断的极化识别方法。仿真分析表明后两种方法的效果突出,可行性高。

Abstract

For effect passive radar target identification, a new method based on the difference of radar polarization was introduced. The representation of different polarization radar was analyzed, a variation of polarization identification method was proposed, which judge the polarization by analyzing the instantaneous direction of polarization and its one and second-order differential characteristics. According to the time domain characteristics of different polarization radar signal received by orthogonally polarized antenna, identification programs based on the minimum amplitude output criteria and the amplitude and phase judgment were put forward. The simulation analysis verified the effectiveness of the last two methods.

Key words： polarization recognition; virtual polarization; minimum amplitude; orthogonal antenna
