| Abstract: | With the rapid development of Beijing urban construction,more and more the land subsidence in the plain area becomes severe.Interferometric Synthetic Aperture Radar（InSAR） has much more advantages with macro-region,quick-speed,high-precision and short-periodicity,and it can provide convenient and efficient technical methods for monitoring the land subsidence.This paper uses SAR data from ENVISAT-1 satellite to monitor the land subsidence of Laiguangying area of Beijing from 2004 to 2005,and get the monitoring results through InSAR technology.The analysis results show that it is feasible to monitor land subsidence in Beijing plain area with InSAR technology. |
