Acoustic Timefront Scattering due to Internal Waves in PhilSea10
Abstract
This project seeks to quantify the effect of sound-speed variability due to internal waves on the scattering of acoustic timefronts and to efficiently and accurately model this variability at multiple depths and ranges in the highly dynamic ocean environment of the Philippine Sea. Random matrix theory will be applied to produce acoustic timefronts that incorporate scattering due to internal waves using the statistics of sound-speed variability in study region. The validity of this approach will be assessed by comparison with acoustic data collected both at a distributed vertical line array (DVLA) and on gliders at various ranges and depths relative to moored sources during the ONR-sponsored PhilSea10 experiment. The ability to efficiently predict these acoustic arrivals and the scattering due to internal waves will lead to the development of new processing techniques to facilitate acoustic tomography using fixed and mobile platforms.
