Simulating Wave Disturbances using Directional Energy Sea Spectra for Spatial Wave Profiles in Time

This paper outlines a technique used to approximately Simulate the sea, for short and long crested waves. Depth effect are included since this study grew out of a previous study looking into the control of shallow running torpedoes. Random time histories with given stochastic properties, for simulating the motion of adjacent water particles, is provided. The method used produces, at each time step, an instantaneous wave profile, with depth attenuation and various perspectives taken into account. In our case for wave profiles along the body at a torpedo, which allows the influence of the sea motion on individual torpedo sections to be determined.
