Numerical Modeling of Acoustic Propagation in a Variable Shallow Water Waveguide
Abstract
Random variability in shallow water will induce variability in a propagating acoustic field. The general long-term goal of this research is to quantify how random variability in the ocean environment translates into random variability in the acoustic field and the associated signal processing algorithms. The specific long-term goal for the current funding cycle is to develop a predictive capability for the ambient noise notch in the presence of random ocean internal waves. The scientific objective of current effort is to understand the effect of internal waves on the ambient noise notch. The ambient noise notch is a trough in the noise directivity pattern that is observed under certain circumstances.
