Detection of single scatterers in correlated clutter using multi-channel SAR interferometric data

In this paper, the detection of single persistent scatterers, exploiting multi-pass interferometric SAR acquisitions, is addressed. A Generalized Likelihood Ratio Test (GLRT) approach that takes into account the presence of correlated clutter is proposed and compared with the case in which clutter is assumed to be white. To assess the performance of the proposed approach, detection results obtained on simulated and real data are presented.
