A New Absorption Coefficient Expression for Use in Sonar Range Prediction

Abstract

Several different expressions are available for the absorption coefficient of sound in seawater. This study has resulted in an improved absorption loss coefficient expression for use in sonar range prediction. Computations were carried out to determine the errors which might result from the use of the alternative absorption coefficient expressions. It is demonstrated that significant differences in the predicted detection range can occur when inexact expressions are used.
