Accounting for Ocean and Seabed Variability in Oceanic Waveguide Parameter Estimation
Abstract
The broad objectives of this grant were to enhance knowledge of underwater sound propagation in geospatially and temporally varying shallow water waveguides. More specifically, the work was focused on experimental techniques for measuring the sound field emitted by a point source or sources at ranges and depth in a shallow water waveguide. Information extracted from these measurements, in the form of normal mode characteristics, would be used as the basis for inferring geoacoustic parameters of the waveguide. During the course of this work, novel signal processing approaches and new inversion methodologies were developed and reported in the scientific literature and at international conferences. The primary data set considered was collected as part of the ONR Shallow Water 2006 experiment.
