Abstract

In this paper, phased multiple-input-multiple-output radars (known as PMRs) that transmit frequency diverse orthogonal signals with full overlapped sub-arrays are studied. At first, the Optimal Detector of PMR is designed by assuming Heterogeneous Clutter and random target scattering coefficients. Then, for the Optimal Detector, the closed-form detection probability and false-alarm rate are computed. At the end, the power assigned to the orthogonal signals is optimized analytically based on the convex optimization framework to maximize the detection probability. The numerical simulations show that the Optimal Detector is a joint spatial-temporal filter that attenuates the clutters considerably by effectively combining orthogonal signals in order to to improve the PMR detection probability in comparison with the phased radar (PR). Furthermore, simulation results illustrate that optimal power assignment in the form of orthogonal waves, based on the statistics of the target scatterings and that of the clutter, improves the detection performance of the PMR in comparison with the conventional equal power assignment methods.
