Study of the Coherence of Acoustic Fields of High-Frequency Noise Sources in a Randomly Inhomogeneous Ocean

A model is been developed for the coherence of high-frequency hydroacoustic fields of noise sources in a randomly inhomogeneous ocean. We analyze the dependences of the coherence of hydroacoustic fields of noise sources on the mutual position of the source and receiver system, the type of waveguide,...

Zusammenfassung:A model is been developed for the coherence of high-frequency hydroacoustic fields of noise sources in a randomly inhomogeneous ocean. We analyze the dependences of the coherence of hydroacoustic fields of noise sources on the mutual position of the source and receiver system, the type of waveguide, and the parameters of random inhomogeneities of an oceanic waveguide. We discuss the possibilities of underwater acoustic observation.
