Development and Application of a Three Dimensional Coupled-Mode Model
Abstract
The over-all goal of this research is the development of an accurate and reliable propagation model applicable to environments which exhibit strong range dependence in all three spatial dimensions. The objective of this current work is to gain an understanding the physics of propagation in continental shelf areas, specifically horizontal refraction and mode coupling induced by three-dimensional inhomogeneities in the waveguide. Of particular interest is the environment of the South Florida Test Facility (SFTF) for which significant horizontal multipath arrivals have been observed [Heaney and Murray (2009)]. A coupled-mode approach is chosen for this work because the field decomposition into modal eigenvalues and amplitudes can provide insight into the effects of environmental inhomogeneities on the acoustic field.
