The Requirement of Range Sidelobe for Dualfrequency Precipitation Radar on FengYun-3 Precipitation Measurement Satellite

摘要：

Pulse compression as one of the key technologies for the dual-frequency precipitation radar (DPR), which will be installed on Chinese FengYun-3 (FY3) Precipitation Measurement Satellite, is being studied. Since the backscattered echo of the sea surface is much stronger than the rain echo, the surface clutter can also contaminate the rain echo through the range sidelobe. In this paper, the model of surface clutter interference with the FY3 DPR is built, and the formulations of computing sea clutter with considering the effect of range weighting function are deduced. Based on the analysis of sea clutter, the requirements for range sidelobe level of the FY3 DPR are proposed.
