520 | 3 |a"The paper considers various methods of frequency-domain beamforming for a line array of hydrophones. The line array geometries are restricted to uniform sensor spacings (i.e. filled array) or a geometry in which sensors are eliminated from the filled structure (sparse array). The methods to be examined include the conventional phase-to-plane beamformer (CB), the data-adaptive Minimum Variance beamformer (MVB), and the Principal-Solution beamformer (PSB)"--Abstract, page ii. |
