Applications of Quantum Chaos Concepts to Long Range Ocean Acoustics
Abstract
The long-term goals are: 1) to take advantage of the ever-changing ocean environment's effects in order to provide a more complete understanding of long-range acoustic pulse propagation, 2) to understand the extent of fundamental limitations on ray-based acoustic tomography of particular interest is the breakdown range of semiclassical methods, 3) to develop the theory of the statistical fluctuations of the wavefield, and 4) to address important basic physics issues that arise in the ocean problem, but within a more general wave propagation in random media context. There are three primary scientific objectives of this work: 1) to begin developing a geometric acoustics theory that addresses parametrically varying ocean environments in the presence of raychaos, determines what information survives under such conditions, and determines how to extract it, 2) to develop the geometric acoustics theory of wavefield fluctuations, and 3) to determine the sensitivity of acoustic wave#elds to relevant ocean environment parameters thereby connecting the scale of changes in the ocean to range scales of wavefield correlation decay.
