Abstract:

Wide swath SAR (WSM) has some characters such as wider swath and short interval so that it can be applied widely to monitor deformation, especially it has largo foreground for monitoring slowness deformation.Depessing baseline and DEM error is a key choke point for ScanSAR interferometry.In this paper, ScanSAR imaging principle and error elements are analyzed, in allusion to wide swath SAR interferogram of bam earthquake, influence magnitude of SRTM3 and GDEM for ScanSAR interferometry is compared each other.,at the same time, results of ScanSAR interferometry which use Envisat orbit data ofthree different kinds are studied, in the end ,some referenced and important conclusions are gained.
