Abstract
In the presence of significant direction-of-arrival (DOA) mismatch, a robust Capon beamforming approach is proposed. The basic idea of the proposed method is first to estimate a set of the desired steering vectors corresponding to DOAs coming from a DOA uncertainty region by using the uncertainty set based approach, then a Bayesian approach is employed to obtain the weight vector.
