A Method for the Measurement of Horizontal Ocean-Noise Directionality.

摘要

Shipping noise dominates in the ocean at lower frequencies and can be resolved by a horizontally directive system into targets and lower noise areas where enhanced ASW detection becomes possible. A method is described for measuring the horizontal ocean noise directionality with a line array system that is towed in a tight circle. Left/right ambiguities are resolved by processing multiple beams from the array. (Author)
