Vertical Discrimination in the Sound Channel,

Abstract

This report describes the theory underlying vertical discrimination for vertical arrays on the sound-channel axis. It presents full wave-propagation calculations, including diffractive effects in the parabolic approximation, that quantiatively predict the behavior of finite arrays, even near caustics. These results confirm experimental observations and provide a single, approximate rule for the length of a vertical array necessary to distinguish between two acoutic sources. The formula is independent of range. Keywords include: Acoustics, Vertical arrays, Vertical discrimination, and Sound channel.
