摘要：

Optimum beamforming of a line array of either two-or three-element closely spaced hydrophone clusters is considered. The objective is the cancellation of convective noise due to the excitation by the turbulent boundary layer. Expressions for array gain using both uniform and optimum cluster-element weighting are obtained. Suboptimum realizations of the optimum cluster-element combining schemes are proposed that suggest simplified hardware implementations. © 1979, Acoustical Society of America. All rights reserved.
