Alenia Spazio activities on SAR interferometry: applications on scientific missions

Alenia Spazio has developed a SAR interferometric processing able to obtain 3D images of observed area using two complex images (SLC-Single Look Complex). This paper describes the most significant steps of this processing detailing some features that lead to a relevant result improvement toward classical methods. The whole processing was applied to some images coming from scientific missions like ERS1 and XSAR: some results are presented.
