Scintillation indices of acoustic waves forward scattered by a rough surface are obtained from numerical techniques leading to both accurate and approximate results in two‐dimensional (2‐D) and three‐dimensional (3‐D) geometries. The Kirchhof

Three types of statistical fourth moments of acoustic waves forward scattered by a randomly rough ocean surface are derived and numerically evaluated. The first one is related to the scintillation index which characterizes intensity fluctuations. The

A shallow water, high-frequency acoustic experiment was conducted off the coast of Panama City Florida during August 1991. Acoustic measurements of surface forward scattering, surface reverberation, and direct path intensities were made utilizing two

Various fourth moments of the acoustic wave field forwardly scattered by a rough ocean surface are evaluated. The fourth moment at the same position is related to the scintillation index. The fourth moments at two positions can be used for extracting

Deconvolution is a mathematical technique for improving the resolution of spectra. Deconvolution can be done in either signal space or frequency space. Both methods were attempted after special adaptations of the algorithms were carried out in order

Experimental data and predicted propagation loss from three shallow‐water test sites with highly varied sediments are compared for frequencies from 25 to 800 Hz. The predicted loss was obtained using normal‐mode and adiabatic normal‐mode models

A coupled-mode approach is applied to examine the spatial coherence of the acoustic field in an inhomogeneous waveguide. The formulation derived is a matrix analog of the equations resulting from application of strong fluctuation theory to propagatio

A simple model of reverberation due to near‐surface bubbles is applied to compute the surface backscattering strength due to a bubble layer. Results obtained using measured bubble data are compared with experimentally measured surface reverberation
