Paper Abstract

A partially correlated polarimetric K-distribution model is presented to characterize statistical properties of multi- look polarimetric SAR data acquired over building-and-road- densely-distributed urban areas. The model is a generalization to the usual polarimetric K-distribution one and is formulated in terms of the matrix product model in which different texture variable s are assigned to different polarization channels. The joint distribution of these texture variables are assumed to be partially correlated Gamma. Testing of the generalized K-distribution model was conducted using NASA/JPL polarimetric SAR data of a building-and-road-densely-distributed urban area, showing that the generalized K-model is more precise than the usual K-model in characterizing statistical properties of complex urban polarimetric SAR backscattering.
