APPLICATION OF POLARIMETRIC TECHNIQUES IN DINSAR PROCESSING FOR SPACE BORNE SUBSIDENCE MONITORING

摘要

Space borne SAR Differential Interferometryrn(DInSAR) is a technique widely used to retrievernterrain subsidence from extensive areas with highrnspatial resolutions. Lately SAR satellites with fullrnpolarimetric capabilities have been launched, such asrnRadarsat-2 and ALOS. The objective of this work isrnto exploit this richer data to increase the quality ofrnthe DInSAR subsidence results. In particular arndataset of Quad-Pol SAR images from the satelliternRadarsat-2 will be exploited, following differentrnstrategies depending on the phase quality estimator.
