Spatial and temporal variability of sound signals in shallow water with parameters varying in horizontal plane

Abstract

In the oceanic waveguide with parameters varying in horizontal plane (for example bathymetry - in area of coastal wedge, slopes and canyons, or in area of varying water layer - in the presence of nonlinear internal waves or temperature fronts, or in presence of both these effects) there is significant horizontal refraction or redistribution of the sound field in horizontal plane. Due to waveguide dispersion (dependence of modal propagation constants on frequency) it is possible to observe different spatial and temporal variations of the sound signal. It can be manifested in non stationary interference pattern, arrival time variations, variations of spectra etc. These effects can be used to solve different inverse problems especially by using horizontal and vertical line arrays.
