Abstract: In order to realize the optical detection of the underwater target, in this paper the optical parameter inversion of the sea surface wave was mainly carried out based on the frequency distribution of the ocean wave. Based on the existing observations and research results of oceanography, the linear superposition based on JONSWAP wave spectrum method was used, combined with the formula of direction function, the height model of ocean waves under different wind conditions was established and the real-time mapping of ocean waves was realized. The simulation results show that the model can better meet the real wave conditions.
