Target detectors using polarimetry are often focused on single (coherent) targets, since these are the ones that can be more simply characterized polarimetrically. The new proposed algorithm is aimed at the more difficult problem of partial target detection (i.e. targets with any degree of polarization). A new feature vector is defined starting from the coherency matrix, and then a perturbation method...
In this study we analyze Radarsat-2 quadruple polarization (quad-pol) mode data acquired over the Everglades wetlands in south Florida. We analyzed the phase information of each polarization mode independently, and obtained similar fringe patterns representing water level changes in all four interferograms. It is surprising, because common scattering theories indicate that cross-polarization (cross-pol)...
Coherence is an important parameter, which appraises quality of topical interferometery fringe and reflects the volume scatter information in InSAR. So it is important for generation of DEM, classification of surface features, estimation of backscatter layers, and quality of differential interferometery processing. In this paper, all kinds of factors, such as spatial and temporal decorrelation, thermal...
