This paper mainly focus on the transmit and receive sensors joint selection problem of distributed MIMO radar in target tracking scienario. Beacause of the limited resources of radars, a subset of radars need to be selected in MIMO radar network at every intance while making the performance to its best. For that purpose, posterior cramer-rao lower bound (PRCLB) is introduced as the optimization criterion...
Taking into account the existence of multipath ionospheric propagation (MIP), a typical phenomenon that skywave over-the-horizon (OTH) radar may encounter, this paper develops the received signal model for a non-point target for multiple-input multiple-output skywave over-the-horizon (MIMO-OTH) radar using the most well accepted physics-based model of the ionosphere. The signal model describes the...
Recent research indicates that one can obtain improved MSE performance from employing a coherent processing approach in MIMO radar with properly placed antennas. This paper demonstrates that the magnitude of these gains decreases with an increase in the product of the number of transmit and receive antennas if the antennas for the noncoherent system are also suitably placed, using a placement which...
Optimum antenna placement is considered for MIMO radar performing velocity estimation. A general optimization strategy for velocity estimation using MIMO radar is derived based on the Cramer-Rao bound analysis. Optimal antenna placement is investigated.We show that when orthogonal signals are adopted for transmission, symmetrically placing the transmit antennas as well as the receive antennas achieves...
