Joint DOD and DOA Estimation Using Real Polynomial Rooting in Bistatic MIMO Radar

Abstract: An algorithm for joint direction-of-departures (DODs) and direction-of-arrivals (DOAs) estimation using real polynomial rooting in bistatic multiple-input multiple-output (MIMO) radar is presented. Compared with the conventional spectral Capon method, the proposed approach estimates the angles by the alternating maximization (AM) algorithm and onedimensional real polynomial rooting instead of two-dimensional angle search to reduce the computational burden. The novel real root-Capon method can perform well even… Show more

“…Several methods, like reduced-Capon [4], signal subspace reconstruction method [5] and ESPRIT [6], for example, have been introduced to estimate DOAs and DODs of targets for bistatic MIMO radar. In [7,8], polynomial root finding techniques are utilized to joint estimation of DOD and DOA in bistatic MIMO radar, suppose that both the transmitter and receiver are uniform linear arrays(ULAs). However, Reference [4] requires additional paired algorithm, while Reference [5] reduces the number of identifiable targets.…”

“…This solution is avoided in [20] resulting in a lower computational load. A polynomial rooting method is used in [21,22]. The pairing, in both approaches, is automatically obtained.…”
