In this paper, we investigate the beam wander in oceanic turbulence taking into account the misaligned displacements caused by slight changes in the position and attitude of the underwater platform. First, we derive the longitudinal distance and radial distance or the misaligned displacements according to the relationship between the misaligned transceivers. Then, we formulate the beam wander variance of a Gaussian beam propagating through oceanic turbulence. Finally, we obtain the beam wander variance in underwater wireless optical communications between the misaligned transceivers according to longitudinal distance. In addition, we express the mean pointing error displacements.

海洋湍流中未对准的收发器之间的无线光通信中的光束漂移。

在本文中,我们考虑到由于水下平台的位置和姿态的微小变化而导致的未对准位移,从而研究了海洋湍流中的波束漂移。首先,我们根据未对准的收发器之间的关系得出纵向距离和径向距离或未对准的位移。然后,我们公式化了通过海洋湍流传播的高斯光束的光束漂移方差。最后,我们根据纵向距离获得未对准收发器之间的水下无线光通信中的光束漂移方差。另外,我们表示平均指向误差位移。
