Sonar beamforming based upon monaural localisation techniques [PDF]

, 1987
Includes bibliographies.Sonar beamforming is usually accomplished using a multi-element transducer array. To obtain high resolution, such a system is costly and complex. In contrast, many mammals are capable of good angular resolution using only a single
