Abstract
We consider the problem of detecting anisotropic scattering of targets from wideband SAR measurements. We first develop a scattering model for the response of an ideal dihedral when interrogated by a wideband radar. We formulate a stochastic detection problem based on this model and Gaussian clutter models. We investigate the performance of three detectors, the conventional imaging detector, a generalized likelihood ratio test (GLRT) detector based on the dihedral anisotropic scattering model, and a sum-of- squares detector motivated as a computationally attractive alternative to the GLRT test. We also investigate the performance degradation of the GLRT detector when using truncated angle response filters, and analyze detector sensitivity to changes in target length. Finally, we present initial results of angular matched filter detection applied to UWB radar measurements collected by the Army Research Laboratory at Aberdeen Proving Grounds.
