摘　　要：雷达低空目标的多径效应严重影响雷达的检测和跟踪性能。在讨论雷达多径信号模型和多径反射机理的基础上,研究了多径效应对低空目标检测与仰角测量造成的影响,详细分析了典型代表性的雷达多径效应抑制技术的研究现状、途径和不足,给出了未来雷达多径效应抑制技术的研究方向,对深入开展雷达多径效应抑制技术研究、解决雷达低空目标检测和跟踪问题具有重要意义。The multipath effect of low altitude targets seriously affects the performance of detection and tracking for radar. Based on discussing the multipath signal model and the multipath reflection mechanism of radar,view study the effect of multipath on low altitude target detection and elevation measurement,analyze the status,approach and shortage of typical representative multipath suppression technology for radar in detail,and present the research direction of future. It is great significant for deeply researching on multipath suppression technology and solving the problem of low altitude target detection and tracking for radars.
