摘要:
D-InSAR 技术能够在大范围内获取地表形变信息 , 但由于卫星侧视几何成像模式、研究区地形地貌等 的影响 , 升降轨 D-InSAR 技术获取的地表形变存在差异。利用双轨 D-InSAR 技术对 6 景升降轨 Sentinel-1A 数据分别进行差分干涉处理 , 得到升降轨不同视线向上台湾美浓 MW 6.7 地震区地表形变图 , 直观地再现了 震区在 2016 年 2 月 6 日地震前后的地表变化。研究结果表明升轨 D-InSAR 监测到台湾地震造成的地表抬升 最大达 16 cm, 降轨 D-InSAR 监测到地表下沉最大达-11 cm, 联合升降轨数据 , 可获得较为真实的研究区地 表形变。
Abstract:
The D-InSAR technology can get the surface deformation information in a wide range, but due to the influence of satellite side-view geometric imaging mode and the topography of the study area,there are many differences in surface deformation obtained by D-InSAR technology. This paper performed differential interference processing on the six-scenes Sentinel-1A data by using the dual-track D-InSAR technology,and obtained the surface deformation maps of the Meinong MW6.7 earthquake area with different sight lines,which visually reproduced the surface changes in the earthquake area before and after the earthquake on February 6th,2016. The results show that the maximum surface uplift caused by the Taiwan earthquake monitored by the ascending orbit D-InSAR technology is up to 16 cm,and the maximum ground subsidence detected by the descending D-InSAR is -11cm. Combining the ascending and descending orbit data,a more realistic surface deformation of the study area can be obtained.
