针对船载平台的特性设计了激光光束跟踪控制策略，并根据船-岸激光通信的特点，设计了155Mbit／s岸上通信终端和船载通信终端完成船-岸激光通信跟踪实验。其中船载终端x轴跟踪残差为3．5μad（d），Y轴为6．7μrad（σ）；平均接收光功率为-29．76dbm，标准差0．35dbm。岸上终端。轴跟踪残差为1．7μrad（σ），Y轴为3．9μrad（σ）；平均接收光功率为-28．18dbm，标准差0．26dbm。实验验证了该跟踪控制策略适用于船载激光通信。

英文摘要：

Ship-borne optical communication is significant as an important node of the future free-space optical communication network. A special beacon tracking control strategy is designed for the ship plat- form. And then a ground communication terminal and a ship-borne terminal are designed based on the features of ship-shore optical communication to conduct the tracking experiment and demonstrate 155 Mbit/s free-space optical communication. The beacon tracking data and received optical power data are recorded. These data show that the ship-borne terminal has an x-axis tracking error of 3.5 μrad （σ） and a y-axis error of 6.7 μrad （σ） ,while the ground terminal has an x-axis tracking error of 1.7μrad （σ） and a y-axis error of 3.9 μrad （σ）. The average received optical power of ship-borne terminal is -29.76 dBm with standard deviation of 0.35 dBm and that of ground terminal is -28.18 dBm with standard de- viation of 0.26 dBm. The experimental results validate that the tracking control strategy is suitable for ship-borne optical communication.
