合成孔径雷达(SAR)差分干涉测量是一种最新的大地形变测量遥感技术方法.利用欧洲空

间局1996年4月15日获取的地球资源卫星ERS-1数据和4月16日获取的ERS-2数据,以及

1997年12月2日获取的ERS-2数据,应用差分干涉测量技术对发生于1997年11月8日的西藏

玛尼地震进行了提取区域形变场的应用研究.从得到的变化检测条纹图中可识别出地表破裂带,并

可定量推算震中周围和两条断裂带附近的变形情况.分析结果表明:断裂为左行平移性质,断裂带

南侧水平错动的最大变形量至少超过2.8 m,北侧水平错动的最大变形量至少超过1.75 m.差分干

涉测量分析结果与地面调查及已有的相关研究资料符合得很好.

-Synthetic Aperture Radar (SAR) interferometry differential is one of the latest geodetic deformation measurement method of remote sensing techniques. Use of the European Space Agency April 15, 1996 acquired earth resources satellite ERS-1 data and the April 16 acquisition ERS-2 data, and ERS-2 data December 2, 1997 acquired the application of differential interferometry technique occurred in November 8, 1997 earthquake in Tibet Mani conducted applied research to extract regional deformation field　the resulting change detection fringe figure surface rupture zone can be identified, and quantitative estimation and deformation around the epicenter near the two fault analysis results show that: the nature of the fracture to the left-lateral, horizontal fracture zone south of dislocation at least exceed the maximum amount of deformation 2.8 m, north of horizontal dislocation of the maximum deformation amount exceeds 1.75 m at least. differential interferometry and ground survey and analysis
