摘要：
A dual-frequency precipitation radar (DPR), which will be the major payload of the FengYun-3 (FY3) Precipitation Measurement Satellite, is being developed in China. This radar will be used to observe Typhoon rain and other precipitation. In the case of spaceborne precipitation radar, the backscattered echo of the sea surface is much stronger than the rain echo. In this paper, the model of sea clutter interference with precipitation measurement of the FY3 DPR. is built, and the effects of sea clutter on the design of the antenna radiation pattern are analyzed in detail. Based on the analysis of surface clutter, the requirements for antenna beam width and radiation sidelobe level are proposed.
