摘　　要：回波信号作为雷达信号处理之源,它的模拟对研究雷达系统仿真具有非常重要的实际意义。在研究雷达回波特性的基础上,获得雷达回波信号的准确表达式,采用映象法将地面分成大杂波单元和小杂波单元,对各小杂波单元产生的回波采用矢量相加以求得相干视频信号,计算整个距离环的回波获得完整的雷达回波信号。最后的仿真结果证明了计算的正确性。Pulse-Doppler radar is wide used, which utilizes the Doppler Shift between the target and the radar to have the target information processed. The simulation of its echo has important significance to make research on the radar system. The echo characteristics were studied and the mapping method was utilized to simulate the air pulse-doppler radar ecbo.
