摘　　要：多径效应严重影响米波雷达探测低仰角目标的性能,这一固有缺陷较大程度制约着米波雷达的深度发展。为了抑制多径效应影响,进一步提高米波雷达对低仰角目标的跟踪测量性能,广大专家学者开展了深入且广泛的研究。在讨论米波雷达多径传播信号模型和多径效应机理的基础上,详细总结分析了具有代表性的低仰角估计技术的研究现状和不足,展望了未来低仰角估计技术的研究方向,对拓宽米波雷达低仰角估计方法研究思路具有重要意义。The existence of multipath effect seriously affects the performance of meter wave radar in detecting low elevation targets,the inherent defect restricts the depth development of meter wave radar to a large extent.In order to suppress the influence of multipath effect and further improve the tracking and measurement performance of meter wave radar for low elevation targets,many experts and scholars have carried out in-depth and extensive research on this issue.On the basis of discussing the multipath propagation signal model and multipath effect mechanism of the meter wave radar,the research siatus and shortcomings of the representative low elevation angle estimation technology are summarized and analyzed in detail,the future research direction of the future low elevation angle estimation technology is prospected,which is of great significance to broaden the research idea of the low altitude target elevation angle estimation method of the meter wave radar.
