Monitoring Land Subsidence in Suzhou City Using D-InSAR Technique
This paper mainly discusses how to monitor the land subsidence in Suzhou city using differential Interferometric Synthetic Aperture SAR (D-InSAR) technique. It firstly introduces the principle and data processing flowchart of D- InSAR. Then it carries out test and gets the land subsidence in Suzhou city using two pass D-InSAR technique. At last, it analyzes some problems which influence the application of D- InSAR in monitoring the urban land subsidence in detail. Keywords-D-InSAR;land subsidenc;2-pass;ERS
