In this paper, we present a GLRT-based adaptive detection algorithm for extended targets with improved rejection capabilities of mismatched signals. We assume that a set of secondary data is available and that noise returns in primary and secondary data share the same statistical characterization. To increase the selectivity of the detector, similarly to the ABORT formulation, we modify the hypothesis...
We consider the problem of adaptive radar detection with a view to provide a detector with high sidelobe signals rejection capabilities. Towards this end, we consider a modification of the adaptive beamformer orthogonal rejection test by enforcing the presence of a fictitious signal under the null hypothesis, orthogonal to the presumed target signature in the whitened space. We derive the generalized...
