Study of the airborne and space-borne microwave imaging radar system

Microwave imaging radar technology, which is represented by the Synthetic Aperture Radar (SAR), is one important tool of observation for the Earth's surface and resource exploration. The Institute of Electronics Chinese Academy of Sciences (IECAS) has been engaged in research and development of the SAR system for more than two decades. In this paper the airborne and space-borne SAR system of IECAS is presented.
