Change detection for multipolarization , multi-pass SAR

This paper develops a unified mathematical theory of change detection for the multi-polarization, multipass synthetic aperture radar (SAR) change detection problem. A generalized likelihood ratio test (glrt) for optimum processing of the measured data is developed; an evaluation of the performance of the optimum glrt is also given in the form of ROC curves (PD versus PFA), quantifying the benefits of multipolarization, multi-pass SAR change detection.
