中文摘要: |
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155 Mbit/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3.5μrad(σ),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 x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 no de of the future free-space optical communication network.A special beacon tracking control strategy is designed fo r the ship platform.And then a ground communication terminal and a ship-borne terminal are designed based on the feat ures of ship-shore optical communication to conduct the tracking experiment and demon strate 155Mbit/s free-space optical communication.The beacon tracking data and received optical power data are reco rded.These data show that the ship-borne terminal has an x-axis tracking error of 3.5μrad (σ) and a y-axis error of 6.7μrad (σ),while the ground terminal has an x-axis tracking error of 1.7μra d (σ) and a y-axis error of 3. 9μrad (σ).The average received optical power of ship -borne terminal is -29.76dBm with standard deviation of 0.35dBm and that of ground term inal is -28.18dBm with standard deviation of 0.26dBm.The experimental results validat e that the tracking control strategy is suitable for ship-borne optical communi cation. |
