Ray Theory Applied to Stability, Fluctuations, and Time-reversal in Deep Water 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, 4) to develop a full ray theory of the many aspects of time reversed wave propagation, and 5) to address important basic physics issues that arise in the ocean problem, but within a more general wave propagation in random media context.
