ABSTRACT:
A system and method for quickly modeling the ideal acoustic sound propagation in a body of water based on current SVP data and the position of the sound source, comprising the steps of: obtaining SVP data for the body of water; determining a depth of a sound source within the body of water; selecting a first ray angle originating from the sound source; calculating a first ray trace for the first ray angle using only the SVP data as environmental inputs; repeating the selecting and calculating steps for second-nthray angles to calculate second-nthray traces for the second-nthray angles; and plotting the first-nthray traces to create a ray trace plot for the body of water relative to the depth of the sound source.
