Year: 2019

Ground‐based synthetic aperture radar (GB‐SAR) is a relatively new technique that can be used to monitor the deformation of large‐volume targets, such as dams, slopes, and bridges. In this study, the permanent scatterer (PS) technique is used to address the issues encountered in the continuous monitoring of the external deformation of an arch‐gravity dam in a hydraulic and hydropower engineering structure in Hubei, China; the technique includes large image data sizes, high accuracy requirements,
