Semiclassical Approximations and Predictability in Ocean Acoustics

Abstract

Our long-term goal is to improve our understanding of the physics of the forward scattering of underwater sound. Of particular interest is understanding limitations on the predictability of underwater sound fields, especially using semiclassical (ray-based) methods. Improving our understanding of the mechanism(s) that contribute to the loss of predictability will lead to improved predictive models. The scientific objective of this work is to understand limitations on the predictability of acoustic wavefields in realistic (range-dependent) ocean environments. Both full wave and semiclassical predictive models are of interest. Both cw and broadband wavefields are of interest. We seek to both develop improved predictive acoustic models and to understand their limitations.
