Abstract :
An electromagnetic model to observe man-made metallic objects in dual-polarized SAR data has been developed. The model predicts that man-made metallic objects and sea surface, being characterized by completely different symmetry properties, call for a different and well-distinguishable HH-HV correlation. Following this rationale, a simple and very computer-time effective filtering technique has been developed to observe man-made metallic objects in full-resolution dual-polarized SAR data. Experiments accomplished over Single Look Complex (SLC) Fine Quad Polarization RADARSAT-2 SAR data confirm the effectiveness of the proposed approach.
