Paper Abstract

New results are presented for optimum coherent detection of signals with random parameters in non-Gaussian clutter. The spherically invariant random vector (SIRV) model is used to characterize the correlated, non-Gaussian clutter samples. A new canonical form for the optimal nonlinear receiver structure is presented. This form incorporates the conventional matched filter which maximizes signal-to-clutter ratio. Closed form solutions for the optimum receivers in Student-t SIRV clutter are presented for the known signal case and in the case of a signal with U(0,2(pi) ) initial random phase. The Student-t clutter example is used to demonstrate the significant improvement in detection probability of the non-Gaussian receiver for the weak signal problem, when compared to conventional Gaussian-based receivers.
