Statistical properties of high frequency acoustic fluctuations induced by rough sea surface

Abstract

Probability Density Function (PDF) of the arrival angle and arrival time of high-frequency sound forward scattering from the rough sea surface are predicted by combining the ray-based and surface-based models. Empirical ocean wave spectrum and empirical model of the sea surface slope are used to model the surface-wave model. We show that environmental parameters and geometrical conditions influence the statistical properties of a wave forward-scattered from the sea surface. To show the validity of the approach, the results are compared with an experimental model. We observe that the proposed model is in good agreement with the expermentally obtained model.
