Three-Dimensional Modeling of Narrow Band Pulse Spreading Using Normal Modes
Physics and Astronomy
Energy from a narrow-band pulse, interacting with a time-varying ocean surface, will be spread into upper and lower sidebands. This can be modeled in a range-independent ocean environment, using normal modes and a coupling scheme based on first-order perturbation theory. The structure of the scattered signal from the two-dimensional Pierson-Moskowitz surface wave spectrum is presented. A normal-mode model with environmental inputs from a shallow sea has been used, and a comparison is made with measured data.
