| 摘 要： | 针对空间无线光通信中捕获、瞄准和跟踪（ATP）技术的粗跟踪系统对信标光斑实时准确跟踪需求,为项目进一步工作提供基础,搭建了无线光通信ATP演示实验系统,分别对粗、精跟踪子系统进行了详细的介绍,利用该系统进行了运动目标的模拟跟踪实验。结果表明：粗跟踪可将运动误差控制在200μrad之内,使光目标始终维持在精跟踪视场内,精跟踪可将系统误差控制在15μrad,可满足通信需求。

| Abstract: | In order to track the beacon facular accurately and in real time for coarse tracking system in free-space optical communication,an experimental system for ATP simulation for free-space optical communication was established.The coarse and fine tracking systems were introduced in detail,and further tracking simulations were performed on this system.The experimental results show that the coarse tracking system can keep the optical target within the field of view of the fine tracking system,and the tracking error is less than 200 μrad.And the tracking error of the fine tracking is less than 15 μrad,which can meet the requirement of communication. |
