The Real-time Simulation of Ocean- wave Signal

In view of the difficulty in simulating the irregular waves, the paper presents an ap- proach to modeling and real-time simulation of ocean-wave signal, according to the long-crest wave theory, and using the technology of OOP. And it makes a seal to kinetic and dynamic characteristics of ocean-wave. The results from the application to the experiment of the ship an- ti-tank are verified adequate to provide credible disturbing power and moment of ocean-wave for the simulation system of ship motion control.
