Application of PIE-SAR in Surface Deformation Monitoring
In this paper,31 images of Sentinel-1A data of Lingshan county,Qinzhou,Guangxi province from 2020 to 2021 were se-lected.PIE-SAR,a domestic remote sensing software,was used to monitor the surface deformation in this area based on small base-line set interferometry technology.The deformation time series was analyzed,and the technical feasibility was verified by comparing with the results of geological disaster zoning.It is helpful to popularize the engineering and domestic application of InSAR technology.
