Broadband Inversion in Shallow Water

Abstract

Largely as a result of the exponential growth in computer technology, we can now embed sophisticated acoustic models in SONAR and ocean-observing systems. We seek to do so in a physics-based sense, with an understanding of what acoustic features can reliably be exploited in the signal-processing algorithms. The specific objectives are to study acoustic propagation in topographically and oceanographically complex areas; to identify robust features in the channel response; and thereby to design robust signal-processing algorithms to both track quiet sources and observe the marine environment.
