A Relationship Between Off-Specular Scattering and Time Spread Phenomena

Abstract

Acoustic signals received from near sea surface explosive detonations were observed to spread in time of arrival due to bottom interaction. The time spread extends considerably beyond the pulse width. In this study, off specular scattering, due to bottom roughness which is thought to be a possible mechanism causing the spreading, is investigated. The scattering theory of Marsh-Kuo is utilized in an attempt to predict the observed time spreading.
