Likelihood Ratio Test for Incoherent Wavelength-Resolution SAR Change Detection

摘要

The paper introduces a new likelihood ratio test for incoherent wavelength-resolution SAR change detection where the assumption of bivariate zero-mean circular Gaussian processes for noise and clutter is replaced by bivariate Rayleigh processes. This replacement brings a higher average probability of detection and/or lower false alarm rate. Hence, the experimental result shows that an average probability of detection is up to 98% with few low false alarms.
