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 longterm 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. In the present funding cycle, the emphasis is on the effects of linear and non-linear internal waves on acoustic propagation in the mid-frequency (1-10 kHz) band.
