Information extraction of Quad-polarization SAR data using polarization decompositions and polarimetric parameters

摘要

Fully polarimetric SAR data can provide detailed information on scattering mechanisms that could enable the target or the structure to be identified. In this paper, we propose a new method for the target information extraction of polarimetric synthetic aperture radar (PolSAR) with the combination of Shannon entropy and polarimetric decompositions. We present the principles and procedures of information extraction based on the characteristics of its scattering mechanism. The performance of this method is evaluated based on Quad-polarization RADARSAT-2 data in Hebei province.
