Synthetic aperture radar (SAR) interferometry is an effective technology for detection and monitoring of slow terrain movements with millimetric resolution. This information is extracted by means of complex techniques from the phase of the signal, which is wrapped modulo 2?? and affected by noise and systematic terms. We have recently proposed a new method, named persistent scatterer pairs (PSP),...
We have recently proposed a new approach, named persistent scatterer pairs (PSP), for the identification and the analysis of persistent scatterers in series of full resolution SAR images. In this technique, atmosphere phase artefacts are effectively eliminated by exploiting their spatial correlation, but without using model based interpolations to remove orbital and atmospheric phase artefacts. This...
Multi-Dimensional (MultiD) SAR imaging is a recent technique, based on coherent SAR data combination, aimed to space (full-3D) and space deformation-velocity (4D) analysis. It is an extension of the concepts of SAR Interferometry and Differential Interferometry and offers new options for the analysis and monitoring of ground scenes. In this work, we discuss the current status and the results obtained...
