Abstract

Data acquired by the new high resolution SAR sensors offer new opportunities in the 3D reconstruction and monitoring of urban area and particularly of individual buildings. Tomographic based SAR imaging is a recent technique that extends the concept of SAR Interferometry to increase the density of measurements by handling situations where multiple stable scatterers interfere in the same resolution cell. The detection of reliable, i.e. persistent scatterers, is a main issue in this technique. With this regard an approach based on the application of the Generalized Likelihood Ratio Test for the detection of single and double scatterers is discussed. Theoretical performances and results of the application to real TerraSAR-X data are presented.
