Abstract
The effects of a model for random bottom structure on acoustic intensity in isospeed shallow water are studied. The randomness results from stochastic variations in bottom density and sound speed in the horizontal direction beneath a plane water-bottom interface. Ray geometry, spreading loss, and bottom loss and phase shift are examined in order to derive formulas for intensity mean and variance. The expressions obtained are sufficiently general to permit their use with different bottom-acoustic models of sound reflection. For illustrative and comparative purposes two such models, those of Mackenzie and Rayleigh, are considered. The distinctive acoustic consequences of bottoms of different density mean, variance, and horizontal correlation are discussed, as are comparisons of results for the two bottom-reflection models. Intensity moments are obtained for differing source-receiver range and water depth. [Work supported by ONR.]
