Abstract

Wide Swath mode (WSM) is also called as ScanSAR, it is character is that synthetic aperture time is shared by circumjacent sub swaths and azimuth resolution is reduced so that large area deformation monitoring for earthquakes is realized. For imaging principle ScanSAR and IM mode are different, process of interferometry also have a lot of dissimilitudes such as coherence, co-registering, correction of atmosphere effects and geoid undulation. In order to make use of ScanSAR data to get wider deformation field, key techniques of ScanSAR interferometry are studied and analyzed in this paper. In the end, 405 km ×405 km deformation fields of Wenchuan and Yutian earthquake are gained by using ENVISAT ScanSAR data. With the application to ScanSAR interferometry in Wenchuan and Yutian earthquake, it is significant for Earth Science research such as large earthquakes and crustal motion.
