基于D-InSAR三轨法的北京平原区地表形变监测
Surface Deformation Monitoring of Beijing Plain Area Based on 3-pass D-InSAR Technique
摘要
Abstract
We described the basic principles of the D-lnSAR 3-pass method to extract the surface deformation and subsidence at the beginning. Taking Beijing Plain area as the experimental area, using and calculating 3 experiment data which was produced during 09/2009～04/2010 that lasts 210 days, we obtained the overall surface deformation of Beijing urban area limits during that period. We compared the InSAR result with leveling measurement method and the monitoring result of the experiment area. The results show that the 3-pass D-lnSAR method can well reflect land subsidence situation of the experimental regional.关键词
