摘要
针对相位和差测角单脉冲雷达系统,提出了一种极化估值与滤波算法。在单一干扰源条件下,建立了全极化空间信号模型,讨论了极化滤波器的设计问题,对极化滤波的效果进行了理论分析和仿真。研究结果表明,在目标和干扰极化域可分的条件下,采用极化滤波可以改善信干比,提高雷达的角度测量精度。
An algorithm of polarization estimation and filtering is studied for the phase sum/difference mono-pulse radar. The full polarization signal model in space is established when there is single interference. The designing of polarization filter is discussed. The performance of polarization filtering is theoretically analyzed and simulated. The research results indicate that the polarization filtering can improve the ratio of signal to interference (SIR) and the angle measurement precision of radar when the target and interference can be distinguished in polarization domain.
