ABSTRACT

ERS, ENVISAT and RADARSAT data were used for InSAR analyses. In order to select a set of suitable ERS scenes a thorough baseline analysis of all ascending scenes acquired over the location (track 406, frame 989) during summer between 1992 and 2001 was performed. It was of interest to find as many data pairs as possible during that time period, yet keep the perpendicular baselines ideally below 100 m, thus reducing contributions of topography on the differential phase as much as possible. Ascending orbit was chosen since its look direction corresponds to the aspect of the slope.
