Scattering effects on ocean acoustics coherence for low-frequency long-range propagation

Abstract
The mutual coherence function (MCF) of the received acoustic field is derived using an analysis based upon coupled mode theory. Separations in transverse horizontal position, time and frequency are treated. The mean horizontal array response and the shape of an ensemble-averaged pulse are evaluated from the MCF. The application is illustrated by computation of the considered effects for rough ocean surface scattering in an upper-sound channel.
