| Abstract: | There was a M7.3 earthquake at the boundary of Yutian County in Hotan Prefecture, Xinjiang, China, on March 21, 2008, which is considerably destructive. The derived deformation field is an effective way to retrieve the geophysical parameters and study the seismic mechanism. Taking the advantace of the wide swath and short revisit time, ScanSAR data were used for Yutian earthquake deformation field. First, the geolocation of Yutian areas was introduced. The process of ScanSAR interferometry was analyzed in detail. At last, the deformation field was derived with the extent of 400 km×400 km. At the same time, interferometry deformation filed of IM is derived with the extent of 100 km×100 km. With the application to ScanSAR interferometry in Yutian earthquake, it is significant for earth science research such as large earthquakes and crustal motion. |
