【摘要】 降水是全球能量/水循环中的重要过程。本文着重分析FY-3气象卫星降水探测能力，展望风云卫星后续规划中降水探测技术的发展前景。分析表明，以FY-3降水星为主星，与其他FY-3极轨卫星组成的FY-3气象卫星降水探测体系，在设计层面上，从载荷类型、数量、通道设置等方面均优于由美国发起并已在轨运行的全球降水测量(Global Precipitation Measurement, GPM)计划核心星的设计性能。FY-3降水星设计装载Ka/Ku双频降水测量雷达，卫星轨道设计覆盖南北纬50°范围内的中低纬地区，对影响我国区域的台风暴雨等强对流天气系统结构具有三维探测能力。FY-3气象卫星星座的降水探测能力为气象防灾减灾提供了基础支撑。更多还原

【Abstract】 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.更多还原
