摘　　要：以跟踪雷达对低空目标的跟踪测量为背景,研究抑制多路径测角误差的方法。首先对多径效应的产生原理、多径模型和多径条件下角误差计算进行了简要介绍,随后对雷达低角跟踪效果进行了仿真分析,提出基于低角补偿的雷达低空目标跟踪方法。最后对补偿效果进行了仿真分析,证明了该方法对提升雷达低角跟踪精度的有效性。The method suppressing the error of multipath angle measurement is studied on the background that the tracking radar tracks and measures low altitude targets.Firstly,the generation principle of multipath effect,multipath model and angle error calculation under multipath condition are introduced briefly.Then,the low angle tracking effect of radar is simulated and analyzed,and a low altitude radar target tracking method based on low angle compensation is proposed.Finally,the compensation effect is simulated and analyzed,which proves that the method is effective to improve the low angle tracking accuracy of radar.
