Broadband Inversion in Shallow Water

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.
