Abstract :
A potential phase unwrapping enhancement by means of a polarimetric coherence optimization is investigated. In particular, the residue density and unwrapped phase after the optimization are compared with the corresponding quantities obtained using single polarization radar data. The study is performed on fully polarimetric data acquired by the portable ground-based system “LISA” developed at the Joint Research Centre
