摘　　要：为解决地物杂波区内降雨回波精确定量化问题,本文利用蒙特卡洛理论,在9836C微型计算机上建立了在不同速度方差的地物杂波区内,对不同速度方差的降雨回波模拟信号经地物杂波抑制器处理后的回波功率损失计算软件系统,并提出实现杂波区内降雨回波精确定量化综合处理方案。Using Monte-Carlo theory,the accurate quantification of the precipitation echo superimposed to the ground clutter was thoroughly studied in this paper. We found a software system (in 9836C microcomputer with Basic language) which is able to calculate the loss ratio value of the echo power of the precipitation signals with different velocity variations superimposed to the ground clutter signals. A synthetical processing scheme which is very helpful for the accurate quantification of the pre-cipitation echo is suggested.
