Abstract
A high resolution one-step algorithm for estimating the angles of arrivals of multiple wideband sources is proposed. For a dense and equally spaced array structure, a bilinear transformation is utilized in frequency domain for coherent signal subspace processing. When compared with existing coherent approaches, the proposed algorithm is noniterative and does not need knowledge of initial estimates of the arrival angles. The performance of the algorithm is presented using simulated data.
