Analysis of Acoustic Propagation and Scattering Data Across Ship Wakes
Abstract
The long-term objective of this work is to contribute to the understanding of propagation and scattering in ship wakes for the purpose of mitigating the potential of detecting and following of wakes by wakehoming torpedoes. NRL has collected wake-acoustics dataset containing a wide variety of measurements across ship wakes. The goal of this research is to analyze the various data contain in that dataset to determine correlations among the various receiving equipment and scenarios sampled in the dataset. Attempts will be made to interpret these data in terms of various scattering theories for propagation in random inhomogeneous media, such as the Born and/or Rytov approximations, in the various regimes of weak to strong scattering. The ultimate goal will be to interpret the scales and magnitudes of bubble clouds and/or turbulence regimes. Within limitations in the scope of this project, however, we will determine what may offer the greatest impact to be made toward our ultimate goal and to address that selected course of action with analysis and publication of the results.
