Abstract

Recently, the coherent scatterers (CSs) technique has been introduced in order to detect scatterers with a deterministic point-like scattering behavior in SAR images. Although the majority of the detected CSs show the typical properties of point-like scatterers, e.g., high amplitude, high interferometric coherence and low polarimetric entropy, some CSs present medium or even high polarimetric entropy. In this paper we study such cases by investigating the possibility that more than one Cs are present insides the resolution cell. We exploit not only the interferometric coherence but also the sublook coherence as a function of polarization states using the PolInSAR formalism and experimental data. For the case that the presence of more than one CS inside the resolution cell is found, the separation of CSs is implemented using a interferometric coherence model. In this work, airborne experimental datasets acquired at L-band by E-SAR system of the German Aerospace Center over the city of Munich in Germany are used.
