array signal processing beamforming steering vector mismatch minimum variance distortionless response
A new method is proposed for robust beamforming with steering vector mismatch of array signals. Introducing a concept of angle robust factor,a nominal signal steering vector is extended to form a steering matrix. Simulation results show that the proposed method can significantly outperform the traditional minimum variance distortionless response(MVDR)in terms of robustness and low sidelobe.
