摘要

摘要: 多路径干扰是对抗机载火控雷达或雷达导引头的有效自卫干扰方式之一,兼具距离、速度、角度维的欺骗干扰效果,目前对该干扰样式难以进行有效识别和抑制。该文提出采用极化雷达导引头工作体制,分析了多路径干扰对雷达的作用机理,建立了多路径干扰和直达干扰信号的回波信号正交极化信号模型,提出了基于信号极化相位统计特性差异的多路径干扰检测方法。该方法物理内涵清晰,实现简单,不仅可以判断干扰信号的存在和类型,还能够鉴别干扰的极化。通过仿真试验,验证了方法的可行性,为有效对抗多路径干扰提供了有益参考。

Abstract: Multipath jamming is an effective self-defense jamming mode used to counter airborne fire-control radar or radar seekers. Multipath jamming has a deceptive jamming effect on the range, velocity, and angle of radar, making it difficult to identify and suppress. In this study, a polarized radar seeker structure is proposed. Based on the mechanism of the multipath jamming effect on radar, orthogonal polarization signal models of jamming and direct arrived signal are established. Next, a method to detect multipath jamming based on statistical property differences of polarization phases is proposed. The physical connotation of this method is clear and easy to realize. This method can be used to determine the presence of a jamming signal and identify the signal pattern and polarization types. The feasibility of this method has been verified via a simulation experiment, thereby demonstrating that the method serves as a useful reference for effectively countering multipath jamming.
