The Spatial Virtual Polarization Filtering Algorithm Based on Dual Polarized Antenna Radar

摘要

摘要: 极化滤波利用干扰信号和目标信号的极化状态差异，可有效抑制有源压制干扰，然而，现有极化雷达需要两路发射通道和接收通道，存在系统复杂、实现代价高等诸多困难。该文提出了一种新体制极化雷达模型极化二元阵雷达，该系统仅需一路发射通道和接收通道即可实现极化测量。基于极化二元阵天线的空域极化特性，建立了有源压制干扰、目标回波的接收信号模型，研究了抑制有源压制干扰的空域虚拟极化滤波算法，仿真实验结果表明：对于窄带噪声调频干扰，信干比(SIR)改善因子能达到20 dB以上。

Abstract: Based on polarization differences between jamming signal and target echo, polarization filter can combat active suppression jamming effectively. However, traditional polarization radars consist of two transmitting channels and receiving channels, facing such limits as system complexity, high realization cost. As a result, a novel polarized radar model named as dual polarized antenna radar is advanced. It can realize polarization measurement using only single transmitting channel and receiving channel. Based on spatial polarization characteristic of dual polarized antenna, received signal models of active suppression jamming and target echo are given, and spatial virtual polarization filtering algorithm to counter active suppression jamming is advanced. Following results can be obtained from simulations: For narrowband noise frequency modulation jamming, Signal Interference Ratio (SIR) improvement factor can be greater than 20 dB.
