Abstract

In this paper, we monitor the surface deformation of Helan Mountains by using the DInSAR (Differential Interferometric Synthetic Aperture Radar) technology and Sentinel-1 SAR data from December 2019 to December 2021. The surface deformation of the Helan Mountain National Natural Reserve with a study area extending to 1935 km2 are observed. The findings indicate that the surface of Helan Mountain Reserve is rising in the east and sinking in the west, with no obvious increasing tendency in the north or south of Helan Mountain. Additionally, the vertical deformation map created by D-InSAR processing is used to monitor two monitoring cycles with significant deformations in June 2020 and December 2021. Furthermore, Helan Mountain has experienced two earthquakes with magnitudes of 3 or greater, according to the differential interference technique. An important decision-making basis for disaster prevention and mitigation can be provided by the deformation data of the ground surface obtained by the InSAR technology.

基于DINSAR技术的地表变形监测

本文利用差分干涉合成孔径雷达(DInSAR)技术和Sentinel-1 SAR数据，对贺兰山区2019年12月至2021年12月的地表变形进行了监测。对贺兰山国家级自然保护区1935 km2范围内的地表变形进行了观测。结果表明，贺兰山保护区地表呈东上升西下沉的趋势，在贺兰山北部和南部没有明显的上升趋势。此外，利用D-InSAR处理生成的垂直变形图监测2020年6月和2021年12月两个显著变形监测周期。此外，根据微分干涉技术，贺兰山发生了两次3级以上的地震。利用InSAR技术获取的地表变形数据可以为防灾减灾提供重要的决策依据。
