Advance in synthetic aperture radar activities

In the recent years synthetic aperture radar (SAR) technique and its application is much emphasized in the field of remote sensing. SAR sensor is being developed as a key geometric data source. This paper presents the main R and D activities of synthetic aperture radar systems in Institute of Electronics, Chinese Academy of Sciences (TECAS). It includes 5 parts of work on airborne SAR, spaceborne SAR, ground SAR processer, basic scientific and technical research and new generation's SAR technologies. These activities are explained and representative examples are described.
