摘要：

A focused minimum variance distortionless (MVDR) beamformer for broadband adaptive beamforming Is formulated and contrasted with the conventional beamformer. The proposed beamformer involves a preprocessor that focuses the signal spaces at different frequencies to a common one and all MVDR beamformer as the narrowband beamformer following the preprocessor. The merits that result as a consequence are improved computational efficiency, of focusing and adaptivity and high beamforming resolution of MVDR with short observation times.
