Abstract:Based on 24 Sentinel-1A ascending orbit images covering the Pu County of Shanxi, PS-InSAR and SBAS technology are used to monitor the surface deformation from January 2019 to December 2019, and the location of the suspected landslides in Pu County are obtained. Range and landslide rate, and the two monitoring results are compared, in-depth analysis of the possible causes of landslide hazards. The results show that the deformation information collected by the two time-series InSAR technology is approximately the same, and most parts of Pu County tend to be stable, with an average annual deformation rate between -10mm/a~+10mm/a. Among them, four suspected landslide sites on both sides of the Rock Line of Bangou Village, near the 015 rural road of Shuiquanya, around Guojia Mountain, and along the Zhaoke Road of Jingziwa Village showed obvious deformation.
