Development and Modeling of Systems for Source Tracking in Very Shallow Water

Abstract

The long-term goal is the development of passive sonar systems for source tracking in very shallow water as pertains to AUV operations and the development of numerical models for acoustic tracking which can be used for AUV mission planning. The objectives are: 1) Develop a two man deployable autonomous passive sonar to add a bistatic capability to the Ambient Noise Sonar (ANS) array developed in previous years, 2) Develop environmental models for tracking error estimation and reduction, 3) Experimentally calibrate and evaluate the acoustic model, the sonar and acoustic tracking capabilities in very shallow water as pertains to typical AUV operations, 4) Extend the concepts developed for AUV passive sonars to provide a small active system for detecting bubbles under breaking waves from an AUV platform.
