Abstract:

LONG-TERM GOALS. Largely because of the exponential growth in computer technology, we can now embed sophisticated acoustic models in SONAR and ocean-observing systems. I would like to do this in a physics-based sense, with an understanding of what acoustic features can reliably be exploited in the signal processing algorithms. OBJECTIVES. The specific objectives are to 1 study acoustic propagation in topographically and oceanographically complex areas 2 to identify robust features in the channel response 3 enhance the acoustic channel-models for efficient prediction of these features and thereby 4 to design robust signal-processing algorithms to both track quiet sources and observe the marine environment.
