Application of SBAS-InSAR technology in geological hazard investigation
It is crucial to timely identify and investigate potential hidden disaster spots in geological hazard investigations for the prevention and monitoring of geological hazards.However,traditional geological hazard investigation methods are time-consuming and labor-intensive,making it difficult to conduct comprehensive investigations in a wide area.In this paper,a detailed investigation of geological hazards in Chengguan Town,Datong County,Qinghai Province was conducted,and the distribution characteristics of geological hazards in the area were obtained.Furthermore,Sentinel-1 radar data was used and processed using a small baseline subset-interferometric synthetic aperture radar(SBAS-InSAR)technology,successfully revealing the surface deformation in the area.Through comprehensive analysis,the changes in key monitoring areas could be accurately identified,thereby improving the efficiency of timely prevention and response to geological hazards.
