Robust adaptive beamforming based on phase extraction

A new robust adaptive beamforming based on phase extraction is proposed in this paper. The steering vector (SV) is firstly estimated by iterative procedure, and then the angle sector of the desired signal can be determined by using the phase information of the estimated SV. By using the estimated angle sector, the interference-plus-noise covariance matrix can be calculated by Capon spectral integration. Simulation results show that the proposed method outperforms the conventional methods.
