Acoustic Techniques for Uncertainty Shallow Ocean Environments

Abstract

The overall long-term goal for this project is to develop engineering tools that are useful to the Navy as it operates in uncertain and/or unknown ocean environments. During the last year, this project has changed its emphasis from predicting the impact of environmental uncertainty on acoustic propagation calculations to determining the utility of a time-reversal-based technique for source tracking and identification in poorly known or unknown ocean waveguide environments. Thus, two sets of long-term goals are stated here.
