Abstract :
A simplified wideband beamforming structure is proposed. Based on this structure, an improved robust Capon algorithm can be used to against look direction errors by employing an estimated array steering vector (ASV). The proposed algorithm is obtained by projecting the nominal ASV onto the signal-plus-interferences subspace, and achieves a higher output signal-to-interference-plus-noise ratio (SINR) compared with the conventional robust Capon beamforming (RCB). Simulation results show the effectiveness of the proposed method.
