An analysis of horizontal refraction in the problem of sound propagation in wedge-shaped oceans

This work is aimed at exploring characteristics of horizontal refraction in three-dimensional sound propagation. The horizontal refraction angle is used as the indicator for evaluating strength of horizontal refraction effects. The horizontal refraction angle, as well as the sound fields, in a series of wedge-shaped ocean waveguides with different bottom parameters are simulated. Furthermore, the influence of bottom parameters on strength of horizontal refraction effects is discussed.
