SARscape® Persistent Scatterers Module for ENVI and ArcView

SARscape® Persistent Scatterers module enables to measure very small ground displacements and to trace the deformation rate related to natural or man-induced phenomena (e.g. volcanic or seismic activity, landslides, subsidence, building collapses, etc.), with excellent accuracy and spatial and temporal detail.

The module deduces the displacement of objects like buildings, bridges, dams, etc. with an accuracy of a few millimeters from SAR data time-series.

The technique relies on the identification in the study areas of a certain number of “coherent radar signal reflectors” (Persistent Scatterers). The processing is then focused on the analysis of the phase history of these very reliable single points (pixels), as opposed to the conventional approaches that process the whole area together.

The Persistent Scatterers module, which supports only SAR data acquired by ERS and ENVISAT satellites, will be released – in the SARscape® 4.0 version - as a stand alone module (i.e. Basic and / or Interferometry SARscape® modules are not mandatory) under either ENVI® or ArcView® software platforms.

The module has been developed by sarmap s.a. and Aresys.
