摘　　要：以大锡特金火山为监测对象,利用4景TerraSAR-X数据,其中两景影像的时间分别为2013-08-16和2013-08-27,另外两景影像的时间分别为2014-08-03和2014-08-14,采用D-InSAR技术获取该火山区域2013年8月期间和2014年8月期间的地表形变量,并和外部DEM数据进行对比实验。通过得到的结果与其他方式获取的火山区域信息等进行对比,验证了D-InSAR技术在形变监测方面的实用性。Taking Great Sitkin Volcano as monitoring object and using four scene data from the TerraSAR-X, we used D-InSAR technique to obtain surface shape variable in the volcano area during August 2013 and August 2014. Two of the TerraSAR-X scenes were taken on August 16 and 27, 2013, and the other two were taken on August 3 and 14, 2014. By comparison with external DEM data, we concluded a reasonable explanation. The comparison with other ways to get information such as volcanic areas verified the practicability of D-InSAR technology in deformation monitoring.
