Abstract Development of synthetic aperture radar (SAR) based satellites provide remedies to major geohazards under critical situations around the world. Sentinel 1A mission with the revisit period of 12 days helps to serve the objective in an effective manner. With the availability of interferometric wide (IW) Swath mode, Sentinel 1A mission is capable of monitoring the surface deformation using interferometric synthetic aperture radar (InSAR) techniques. On 12 November 2017, an earthquake with a magnitude of 7.3 occurred in the Iran/Iraq border lead to the enormous disaster reaching over 500 victims. The study focuses on measuring the deformation caused due to earthquakes by using differential SAR interferometry (DInSAR). VV polarization of Sentinel Data and SRTM DEM are used as an input to GMTSAR for the development of interferogram. Based on the results obtained, it is found that a maximum of 85.1 cm deformation occurred and nearly 1500 km2 of the area is severely affected.

使用 Sentinel 1A Imagery 的基于 InSAR 的地震变形映射

摘要 基于合成孔径雷达 (SAR) 的卫星的发展为世界各地在危急情况下的重大地质灾害提供了补救措施。重访期为 12 天的哨兵 1A 任务有助于以有效的方式为目标服务。随着干涉宽幅 (IW) 幅面模式的出现，哨兵 1A 任务能够使用干涉合成孔径雷达 (InSAR) 技术监测表面变形。2017 年 11 月 12 日，伊朗/伊拉克边境发生 7.3 级地震，造成 500 多名遇难者的巨大灾难。该研究的重点是通过使用差分 SAR 干涉测量法 (DInSAR) 测量地震引起的变形。Sentinel Data 和 SRTM DEM 的 VV 偏振用作 GMTSAR 的输入，用于开发干涉图。
