Precipitation is an important process in the global energy / water cycle． This paper focuses on the analysis of the precipitation detection capability FY-3 meteorological satellites，and looks forward to the development prospect of precipitation detection technology in the follow-up planning of FengYun satellites． The analysis shows that the precipitation detection system of FY-3 meteorological satellites， which is composed of FY-3 precipitation measurement satellite as the main star and other FY-3 polar orbiting satellites，is superior to the design performance of the in-orbit operation core satellite of Global Precipitation Measurement (GPM)mission initiated by the U． S． in terms of load type，quantity，and channel setting． The FY-3 precipitation satellite is designed to be loaded with Ka / Ku dual-frequency precipitation measurement radar． The satellite orbit design covers the middle and low latitudes between 50°N and 50° S． It has three-dimensional detection capability for synoptic systems of strong convective weather such as typhoon-induced rainstorms affecting China． The precipitation detection capability of FY-3 meteorological satellites provides basic support for meteorological disaster prevention and mitigation．
