Paper Abstract

This paper focuses on the geometric applications of the SAR interferometry, i.e. the generation of digital elevation models (interferometric SAR, InSAR) and the monitoring of deformations (differential interferometric SAR, DInSAR). The InSAR and DInSAR techniques have in common most of the processing steps of their procedures. In this paper we describe a general DInSAR procedure for deformation monitoring. Furthermore, we discuss the phase unwrapping, which represents a key processing step for both the InSAR and DInSAR techniques. The second part of the paper describe in depth the DInSAR results based on ERS images, which were obtained on the estimation of the co-seismic field associated with a series of earthquakes occurred in Central Italy in 1997.
