Abstract

4D (space-velocity) SAR focusing is applied to real data acquired over urban areas to determine the position, in 3D, and the deformation velocity of single and double scatterers interfering, at high resolution, in the same azimuth-range pixel. We discuss the procedure required to identify the presence of stable single and double scatterers after the elevation-velocity focusing. Moreover we present a technique for the separation of time series associated with interfering scatterers to measure their possible non linear temporal deformations.
