Synthetic aperture radar (SAR) interferometry is a powerful technology for detection and monitoring of slow terrain movements. Extraction of this information is a complex task. The persistent scatterer pair (PSP) approach was recently proposed to overcome limitations of standard persistent scatter interferometry. The PSP method exploits only the relative properties of neighboring points to avoi...
This study focuses on deformation mapping and monitoring using Sentinel-1 radar data the DInSAR (Differential Interferometric Synthetic Aperture Radar) technique. In particular, a Persistent Scatterer Interferometry technique was used over 15000 km2 of Pyrenees, located in Spain, Andorra France. The main goal is to monitor deformations vegetated mountainous region by exploiting wide-area covera...
Time series of Sentinel-1 data are widely used for monitoring displacements the Earth surface using persistent scatterer interferometry. By default over land, images include two polarimetric channels: VV and VH. However, most works in this application exploit only channel, whereas VH channel is discarded its lower amplitude. Thanks to development interferometry methods, one can integrate multi-...
An Efficient Polarimetric Persistent Scatterer Interferometry Algorithm for Dual-Pol Sentinel-1 Data
With time-series PolSAR images, polarimetric persistent scatterer interferometry (PolPSI) algorithms can obtain optimized interferograms with overall better phase quality than any single-pol channel for ground deformation monitoring. Moreover, the open access of Sentinel-1 data makes it possible applications PolPSI over large regions worldwide. However, optimum scattering mechanism usually has ...
