摘　　要：通过对应用场景中多路径反射模型以及接收信号幅度、时域关系的分析,提出一种基于多峰值组信号匹配的多径信号处理方法。基于对各接收通道到达时间(TOA)的精确测量,以直达波信号首先达到为原则,采用多峰值组匹配技术,实现了直达波束与多径反射波束的区分。测试结果表明所提方法可以实现对多径反射信号的滤除,剔除方位跳变,具有工程应用价值。A multipath signal processing method based on multi-peak group signal matching technology is proposed by analyzing the multipath reflection model and the relationship between received signal amplitude and time domain.Based on the accurate measurement of time of arrival(TOA)of each receiving channel and the principle that the direct wave signal reaches first,the multi-peak group matching technique is used to distinguish the direct beam from the multi-path reflected beam.The test results show that the proposed method can filter the multipath reflection signal and eliminate the azimuth hopping,and has engineering application valuable.
