Acoustics in Uncertain Ocean Environments

چکیده
3) to predict and understand the characteristics of active and passive time reversal methods in shallow ocean waters. Compared to the first two, the third goal is a secondary priority that stems from the legacy of more than a decade of prior work on acoustic time reversal. It is mentioned here because the author of this report does respond to the continuing technical inquiries and collaboration opportunities in this area when potential US Navy interests are apparent and when such commitments do not adversely impact progress toward the first two goals.

Approximating Acoustic Uncertainty in Shallow Ocean Environments
In recent decades, sophisticated computational routines for underwater acoustics have been developed, and advances in computational power have put real time use of these routines in reach for sonar applications. However, the US Navy must often operate in unfamiliar waters where the basic environmental inputs to the computational routines may be uncertain or unknown. In this situation, the value...

A primary goal of this research is to model biological clutter in the continental shelf environments of the ocean. We aim to do this by modeling scattered returns from fish shoals in continental shelf environments using a full field matched filter approach as well as its single frequency approximation. This will help in characterizing clutter and will help distinguish scattered fields of moving...

متن کاملRay Dynamics in Ocean Acoustics
Recent results relating to ray dynamics in ocean acoustics are reviewed. Attention is focussed on long-range propagation in deep ocean environments. For this class of problems, the ray equations may be simplified by making use of a one-way formulation in which the range variable appears as the independent (time-like) variable. Topics discussed include integrable and nonintegrable ray systems, a...
