Role and Development of Spaceborne Radar Remote Sensing
航天雷达遥感的作用与发展

This paper deals with the role of the Seasat SAR, SIR-A and SIR-B in earth science research, which have acquired the spaceborne radar images of the earth surface uniquely. The activities of the active microwave remote sensing in the coming ten years have been described, especially the ALMAZ SAR, ERS-1 SAR, JERS-1 SAR, SIR-C, Radarsat SAR and EOS SAR systems. It is prospected that the 1990's will be the key decade for technical development and geoscience application of the spaceborne radar remote sensing.
