摘　　要：针对米波三坐标雷达实际运用中低空测角不准的问题,提出利用补偿因子对多径信号进行补偿的方法。首先对影响测角精度的地形因素进行分析,针对雷达阵地的地形环境,引入补偿因子,建立补偿因子与地形参数的函数关系,并据此利用补偿因子对多径信号进行补偿。仿真实验结果表明了该方法对抑制多径影响的有效性。In order to solve the problem of inaccurate angle measurement at low altitude in the practical application of me⁃ter-wave three-coordinate radar,this paper proposes a method to compensate multipath signal by using compensation factor.First⁃ly,the topographic factors that affect the accuracy of angle measurement are analyzed,and the compensation factor is introduced to different terrain environments of radar positions,and the functional relationship between the compensation factor and the topograph⁃ic parameters is established,and the multipath signals are compensated by the compensation factor.The simulation results show that the proposed method is effective in improving the accuracy of low altitude angle measurement.
