COMPARATIVE STUDY ON MONITORING SURFACE SUBSIDENCE WITH PS-InSAR AND SBAS-InSAR
PS-InSAR与SBAS-InSAR监测地表沉降的比较研究

Taking the analysis of the surface deformation monitoring of Beijing through 31 ENVISAT image from 2004-2010,as an example,the result of analysis show that the SBAS time-series of the deformation of PS points is little more continuous in space than that of PS and the experimental results show that the result of SBAS and PS are in good agreement and close radically to the monitoring result of Beijing subsidence monitoring site warning forecast system so the result of PS and SBAS is reliable.
