摘要
The articles studies how the correlation characteristics of noise generated by wind sources affect the efficiency of spatial processing of signals received by a horizontal array in oceanic waveguides with a rough sea surface. The array gain values are analyzed for three spatial processing methods: the standard PA method, optimal linear processing, and optimal quadratic processing. Numerical simulation results for winter hydrological conditions in the Barents Sea and Pacific Ocean are presented. The authors focus on dependence of the array gain on the distance to the source. The array gain values calculated using the wind noise model and traditional noise model uncorrelated on its elements are compared.
