Scattering Component Selection and Multi-resolution Detection of Persistent Scatterers in Sparsely Urbanized Areas

Approaches based on the coherent processing of Synthetic Aperture Radar (SAR) data archives acquired over long temporal intervals allows 3D reconstruction/imaging and monitoring of urban areas with very high accuracy on the velocity, e.g. sub-centimetric per year. The technology is rather mature and developed in some cases also at the level of operative services. Nevertheless research is still going on to improve the technology in terms of coverage and reliability of estimated parameters for correct localization and accurate monitoring of targets. With this regard, the application to regions characterized by a mixture of urban and rural areas is of interest. This work discusses the different techniques for filtering and selection of scattering mechanisms and for single and multi-look approaches for the multi-resolution detection of Persistent Scatterers.
