摘　　要：极化抗干扰是雷达干扰抑制的重要技术手段,双极化体制探测目标不仅可以获取较为丰富的极化信息,同时在硬件方面也容易实现。因此,文章结合双极化雷达实测数据开展压制干扰的特性分析与抑制研究。基于噪声调频、梳状谱、间断噪声和函数扫频几种压制干扰下信号的分析,结合目标与干扰在极化特性上的差异,引入斯托克斯矢量等极化参数进行双极化干扰滤波设计。最后,用自适应极化对消(Adaptive Polarization Canceller,APC)迭代滤波算法与本文方法进行了对比分析。实验结果表明,文章所提方法能够有效抑制干扰,提高目标检测性能,显示了良好的工程应用前景。Radar polarization anti-interference is a crucial technique in radar interference suppression.Dual-polarization system detection of targets not only provides relatively rich polarization information,but is also easy to implement in hardware.Hence,the characteristic analysis and suppression research on blanketing jamming based on measured data from dual polarization radar is conducted.With the analysis of several types of the blanketing jamming,dual-polarization interference filtering based on polarization parameters such as Stokes vector is proposed,resulting from the difference in polarization characteristics between the target and the interference.Finally,the adaptive polarization canceller iterative filtering algorithm is used to compare and analyze with the proposed method.The experimental results show that the proposed method can effectively suppress interference and improve target detection performance,which has a broad engineering application prospect.
