Abstract:
1. A method for simulating an acoustic field of an acoustic waveguide, the method comprising: generating, by a processor, a sound speed profile of the acoustic waveguide, the acoustic waveguide having a region of a first fluid within a second fluid, the region of the first fluid including a volume of the first fluid, the first fluid having a different acoustic index of refraction than the second fluid; applying the sound speed profile and predetermined parameters of a sound source and a receiver to a parabolic equation (PE) model of sound propagation in the acoustic waveguide; and determining, by the processor, the acoustic field of the acoustic waveguide from the PE model, such that the acoustic field includes an interference pattern from interference between an acoustic signal of the acoustic source and at least one signal refracted by the region of the first fluid.
