Abstract :
In this paper we investigate the problem of detecting single coherent scatterers in multidimensional (elevation-velocity) SAR imaging. We exploit both phase and amplitude information and a GLRT approach. Multipass/multiview SAR data are used and performances are assessed referring to two different models for the scatterers: deterministic and Gaussian model.
