Modeling the spatial and frequency distribution of narrow-band acoustic signals scattering from the ocean surface

摘要

Energy from a narrow-band acoustic signal, interacting with a time-varying ocean surface, will be scattered in the spatial and frequency domains. This scattering can be modeled using range-independent normal-mode theory and a coupling scheme based on first-order perturbation theory. Simulations will be performed using a two-dimensional surface wave spectrum.
