摘要：传统的地表形变监测成本高、耗时长、效率低，利用 SBAS-InSAR 技术可以进行时序性地表形变监测。本文运用 SBASInSAR 技术，获取 2020 年 1 月耀2021 年 10 月 44 景 sentinel-1 升轨数据，通过 SBAS-InSAR 技术得到研究区的地面形变速率为7.461mm/year 耀 -16.794mm/year，结合 6 个典型形变点对研究区的变形进行探究，研究结果显示：长水机场主体建筑物抬升，四周处于沉降状态，该研究对长水机场的安全运营具有重要意义。
Abstract: The traditional surface deformation monitoring is costly, time-consuming and inefficient. SBAS-InSAR technology can be used for temporal surface deformation monitoring. This article uses SBAS-InSAR technology to obtain the sentinel-1 ascending orbit data of 44 scenes from January 2020 to October 2021. Through SBAS-InSAR technology, the ground deformation rate of the study area is obtained to be 7.461mm/year to -16.794mm/year. Combined with six typical deformation points, the deformation of the study area is explored, the research results show that the main building of Changshui Airport is lifted and the surrounding area is in a settlement state. This study is of great significance for the safe operation of Changshui Airport.
