Reduced-dimensional angle estimation in bistatic MIMO radar system

An algorithm for reduced-dimensional angle estimation in bistatic Multiple-Input Multiple-Output (MIMO) radar system is presented. By utilizing the characteristic of Kronecker product, two-dimensional search of Capon/MUSIC can be reduced. The direction-of-arrivals (DOAs) and direction-of-departures (DODs) can be obtained by one-dimensional search and eigenvectors corresponding to the smallest eigenvalues, respectively. Furthermore, the angles of targets can be paired automatically. Simulations which demonstrate the analytical derivations are provided.
