Study of the polarimetric SAR interferometry coherence optimization

Polarimetric and interferometric SAR is the combination of PolSAR and InSAR. In [5], a general formulation is derived for coherent interferometry using polarized waves. Based on this formulation, the coherence optimization problem can be solved to obtain the optimum scattering mechanisms that lead to the best phase estimates. In this work, the PSO algorithm is employed to improve the SAR interferometry coherence optimization.
