Deformation Monitoring of Large-Scale Rockfill Dam Applying Persistent Scatterer Interferometry (PSI) Using Sentinel-1 SAR Data

The Persistent Scatterer Interferometry (PSI) analysis accurately estimates the change over time of only the PS points on the ground surfaces using the time variation of the phase change of pixels with a small amount of noise called Persistent Scatter (PS).The riprap on the external surface of a rockfill dam is well reflected by radar, and since many PS points can be obtained over the entire exter...
