Ortho-rectification and terrain correction of polarimetric SAR data applied in the ALOS/Palsar context

Abstract

Methods for terrain correction of polarimetric SAR data were studied and developed. Ortho-rectification resampling and amplitude correction utilized Stokes matrix data. The Stokes matrix of thermal noise was subtracted before amplitude normalization. Application of an azimuth-slope correction algorithm resulted in slightly narrower distribution of orientation angles compared to input data.
