摘要
为了实现对水下目标的光学探测，文中主要通过海浪空间频率分布特征对海面浪形进行光学参数反演，从海洋学现有的观测和研究结果出发，利用基于JONSWAP海浪谱的线性叠加方法，结合方向函数相关公式，建立了海浪在不同风力条件下的高度模型，并实现了海浪的实时绘制，仿真结果表明，该模型能较好地符合真实海浪情况。
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.
