提出了一种针对主瓣压制干扰的空域虚拟多通道并行极化滤波技术.利用天线在空域扫描时的极化慢变特性,对接收到的干扰信号进行处理,获得正交极化回波与极化状态的估计,然后以最佳极化进行极化滤波,以达到抑制噪声干扰的目的.通过采取并行处理,该方法能够消除仰角估计误差对抑制性能的影响.理论分析和仿真表明,该方法可使单极化雷达具备极化信息处理能力,进而获得较大的性能提升.
A spatial multi-channel virtual parallel polarization filtering technique aiming at suppression of mainlobe jamming is proposed.Antennas are used to process the received interference signals by using the slow polarization changing characteristics of the antenna in space-domain scanning, and the orthogonal polarization echo and And then polarization filtering is performed with the best polarization to achieve the purpose of suppressing the noise interference.The method can eliminate the influence of the error of the elevation estimation on the suppression performance by taking parallel processing.The theoretical analysis and simulation show that the proposed method The method allows the polarization radar to have the polarization information processing capability and thus obtain a larger performance improvement.
