SummaryObjective: We investigate the detection performance of multiple scatterers, lying in the same range-azimuthresolution cell, obtained using a (Constant False Alarm Rate) CFAR approach. Method: In particular we exploit the sparsity assumption, which is always verified in practical cases, and we propose a Generalized Likelihood Ratio test (GLRT) searching for the best support of the unknown signal which matches the data. The test consists of two steps: first the presence of scatterers is detected, secondly the determination of the number of scatterers and the estimation of their positons is performed by means of a signal support detection-estimation operation. The test proposed is investigated both at the nominal system resolution and in the super-resolution cases. The method will be also compared with other approaches presented in the literature. Data requirements: TerraSAR-X data will be used to show the detection performance of the proposed method. In particular multi-pass SSC TerraSAR-Xacquisitions are required. Deliverables:The results will be submitted for publication on a scientific journal.The research will be funded by local research project.
