Propagation of Low-Frequency, Transient Acoustic Signals through a Fluctuating Ocean: Development of a 3D Scattering Theory and Comparison with NPAL Experimental Data
Abstract
The long-term goal is the development of a new, 3D, modal theory of low-frequency, long-range sound propagation through a fluctuating ocean, including both CW and transient acoustic signals and comparison of theoretical predictions with NPAL experimental data. The objectives are: 1) To develop a 3D modal theory of broadband sound propagation though a fluctuating ocean, including analysis of the coherence function for transient acoustic signals and temporal coherence. 2) To develop computer codes for calculation of the horizontal and vertical coherence functions of transient acoustic signals and temporal coherence. 3) To compare theoretical predictions with the 1998-1999, 2004, and 2009-2011 (in the Philippine Sea) NPAL experimental data.
