摘　　要：为了研究激光雷达水深探测时,受海面风影响的波浪变化对激光入射角的影响,文章基于JONSWAP海浪谱与方向函数相关公式构建三维海浪模型,考虑浅海波浪传播的方向性和周期性呈规律传播状态,引入小振幅波理论模型,建立双模型叠加的海浪在不同风速等级下的高度模型以及水下激光脚点的坐标。仿真结果表明,构建的模型能较好地仿真海浪变化情况。To study the effect of wave variation on laser incident angle in bathymetric detection by lidar,the wave variation is influenced by sea surface wind,in this paper,a three-dimensional ocean wave model is constructed based on the correlation formula of the JONSWAP ocean wave spectrum and direction function,considering the regular propagation state of the direction and periodicity of the shallow sea wave propagation,the theoretical model of the small amplitude wave is introduced,and the height model of the ocean wave superposed by the two models under different wind speeds and the coordinates of the underwater laser foot point are established.The simulation results show that the proposed model can reasonably capture the variation of ocean waves.
