Abstract

With the launch of ESA’s Sentinel-1 SAR mission, focus is on wide-area Persistent Scatterer Interferometry (PSI) for deformation monitoring. Here, first, non-urban areas also need to be processed; and this requires robust algorithms for scatterer selection, network construction and inversion, and atmospheric phase removal. Second, the computational load can be very high, due to which, the processing is usually divided into overlapping blocks and merged later. This can however lead to spatial error propagation. This paper presents algorithms which have been developed for a robust PSI reference network estimation.
