Three-Dimensional Ocean Noise Modeling
Abstract
The objective of this project is to validate the use of an efficient computation noise model for accurately predicting the three-dimensional spatial properties of ocean ambient noise fields in arbitrary, realistic and complex domains. This can be achieved by applying the reciprocity principle of the wave equation to the complex pressure field calculated by a Nx2D or cylindrical three-dimensional parabolic equation (PE) propagation model. The probability distribution function of the noise power spectral density, and the horizontal and vertical coherence can be calculated from the PE model output. Additionally, a theoretical framework for describing the noise field in three-dimensional longitudinally invariant environments (in particular, an infinitely long Gaussian trench) is described using the method of normal mode decomposition.
