Monitoring of land surface deformation in Beijing with time-series InSAR technique based on multi_band InSAR data using RADARSAT-2 and TERRASAR-X

摘要

Taking the typical subsidence area in Beijing as the study areas, the study applied the Persistent Scatterer InSAR (PS-InSAR) to process two SAR datasets, which was acquired by TERRASAR-X and RADARSAT-2 satellites, at ascending and descending orbits respectively. Eventually, the land subsidence over this area was obtained. Compared the two results, the monitoring results showed that the two datasets had high consistency. This Study have shown that the use of PS-InSAR monitoring is accuracy and reliable and it can devote to the effective monitoring of Beijing area land subsidence.
