Abstract:
SAR images of urban areas are characterized by strong geometrical distortions (layover, foreshortening, shadowing) and a high diversity of mainly man-made scattering mechanisms. In order to simplify the analysis of SAR images in urban regions the Coherent Scatterers (CSs) technique has been proposed for the detection of scatterers with point-like behaviour. These deterministic scatterers allow the extraction of information in a simpler and more direct way. In this work, the detection and characterization of CSs at different frequencies and different polarizations is addressed. For that, airborne data acquired at L-, C- and X-band by the E-SAR system of the German Aerospace Center (DLR) over the city of Munich in Germany are used.
