Abstract:2012 is the ten years anniversary of the first launch of microwave remote sensor of China. Since with the “multi-mode remote sensor”onboard of Shenzhou IV spacecraft, China has launched several microwave remote sensing satellites, including Lunar Exploring satellites Chang’E-1 and Chang’E-2, meteorological satellites FY-3 serials, oceanic dynamical environment satellite HY-2，SAR satellite HJ-1C, etc. Besides those, several microwave remote sensing satellites have been set into pre-launch research. We have made great development in space microwave remote sensing technology with a completed system composed of theoretical research, project engineering, and comprehensive applications, which serves as an advanced technological method for economical construction and national security of China. This article reviews the forty years development of microwave remote sensing in China, especially the experiences and achievements acquired in recent ten years in space microwave remote sensing, and discusses the development routine, future directions, and some problems existed now, further more, it gives some innovative ideas and suggestions for future development.
