cqvip:Research on Key Technologies of Precise InSAR Surveying and Mapping Applications Using Automatic SAR Imaging Xinming TANG,Tao LI,Xiaoming GAO,Qianfu CHEN,Xiang ZHANG Satellite Surveying and Mapping Application Centre,Beijing 100048,China Abstract:Precise interferometric synthetic aperture radar (InSAR) is a new intelligent photogrammetric technology that uses automatic imaging and processing means.Precise InSAR has become the most efficient satellite surveying and mapping (SASM) method that uses the interferometric phase to create a global digital elevation model (DEM) with high precision.In this paper,we propose the application of systematic InSAR technologies to SASM.
