Support-detection 5-D SAR tomography

In this paper we extend the Fast-Sup-GLRT Detector, designed for SAR tomography (3D-SAR), to the detection of multiple scatterers that can exhibit time deformation. It assumes at most K
_max
different scatterers in the same range-azimuth resolution cell with a phase model that takes into account phase variations due to the deformation and/or dilation of the scatterer(s). Results on simulated and real data are presented to validate the proposed approach.
