Abstract
on the basis of discussing virtues and defects of traditional ocean wave spectrum modeling method, this paper proposes a new method for accurate real-time ocean wave simulation. It builds the basic ocean wave model based on improved Gerstner wave. To resolve contradiction between accuracy and real time, it deduces discrete FFT algorithm model of ocean wave, and acquires parameters needed in ocean wave FFT model by sampling wave vector spectrum. The result of simulation proves this method is feasible and effective.
