Identification of Geological hazards in pumped Storage Power Station based on ALOS-2 and Sentinel-1A

Aiming at the hidden danger points of geological disasters during the construction of Zhenan pumped storage power station in Shaanxi Province, 10 scenes of ALOS-2 orbit reduction data from April 20, 2020 to May 19, 2021 were obtained, and 66 scenes of Sen tin el-1A rising orbit data from January 18, 2019 to May 19, 2021 were obtained. the interference point target analysis technology was used to identify the hidden dangers of geological disasters in the target area. The recognition results are superimposed on the high-view optical satellite remote sensing data in April 2021, and the hidden trouble points are identified by combining the DEM data. A total of 23 hidden dangers of landslides were identified by remote sensing investigation, and on-site verification work was carried out. The verification results show that there are 17 hidden danger points at the scene, and the recognition accuracy is 73.9%. This study provides a new idea for the identification of geological hazards in pumped storage power stations.
