Description of physical effects of acoustic field in a shallow sea waveguide

Year: 2024

Type: article

Abstract: The field of the complex vector of acoustic intensity of a moving tonal low-frequency source in a regular waveguide of a shallow sea is investigated. The following phenomena are considered: phase front dislocations, singular points, an acoustic intensity vortex and the mechanism of its stability, angular momentum of the vortex, vortex rotor. The value of the signal-to-noise ratio has been established at which the appearance of a phase front dislocation and a vortex in the far field of the signal source is possible in a coherent field.
