Numerical Simulation of Targets Deorientation and Its Application to Unsupervised Classification in Polarimetric SAR Images

摘要：

Deorienation theory of polarimetric scattering targets is developed,which transforms the spatially oriented targets into a certain orientation or status, to show the prominence of the generic characteristics of scattering targets. A new set of the parameters u,v,w,ψ is defined and used to describe and classify different targets. Based on the vector radiative transfer (VRT) model of non-spherical particles above rough surface,numerical simulations illustrate the parameters u,v,w,ψ and the entropy H. These parameters are applied to the unsupervised classification in polarimetric images. An AirSAR polarimetric image over Canada s Boreal district is classified into 8 classes and orientation-analyzed.
