A Solution to the Inverse Problem in Ocean Acoustics
Keywords: Marine acoustic modelling, Geophysical inverse techniques
AbstractThe methodology and software developed to reconstruct a vertical sound speed profile as a part of studies on the marine acoustic modelling, using the ray path lengths and the travel time perturbations in tomographic layers are outlined. For a stratified ocean, considering the range independent nature of the medium, geophysical inverse techniques are employed to reconstruct the sound speed profile. The reconstructed profile for a six layer ocean, with five energetic modes, is in good agreement with that of the assumed profile thereby indicating the usefulness of the model. The effect of noise caused by the excursions of the source and receiver moorings; When expressed in terms of travel-time differences, results in the sound speed changes up to 0.1 percent.
