摘　　要：新一代高分辨雷达卫星尤其是TerraSAR-X的发射运行,给时序InSAR分析技术带来新的挑战,得益于其高分辨率特点使得特定目标的短期内微小形变监测成为可能。本文利用2009年3月～2010年1月间27景3m分辨率的TerraSAR-X数据,基于改进的时间序列InSAR技术获得京津城际高铁武清段和北辰段沿线区域地表时序形变特征,并对形变规律及成因进行分析。A new generation of high resolution radar satellite especially TerraSAR-X launched to bring new challenges for time series InSAR analysis technology. Due to its high resolution characteristics,it makes the specific target small deformation monitoring possible in the short term. In this paper, we processed a dataset of 27 scenes 3m resolution TerraSAR-X data ac- quired between March 2009 to January 2010, based on modified time series InSAR technology to extract the area time series land deformation characteristics, along the beijing-tianjin inter-city high speed rail Wuqing and Beichen segment, and we further ana- lyzed the deformation rules and causes.
