ALOS-2 PALSAR-2 scansar interferometry for ground deformation monitoring in Beijing-Tianjin area, Northern China

摘要

Space-borne differential InSAR (DInSAR) technique is an efficient tool for ground deformation monitoring due to its extensive coverage and millimeter level accuracy. With successful operation of Sentienel-1 and ALOS-2, there is increasing interest in exploiting the wide-swath mode of SAR for measuring surface topography and deformation over large area because of its wide coverage and rapid revisit capabilities. In this paper, we present preliminary result of ground deformation analysis in Beijing-Tianjin area by using three ScanSAR mode products of ALOS-2 PALSAR-2 acquired on Sep.10 2015, Oct.22 2015 and Oct.20 2016.
