| 中文摘要: |
| 捕获、对准、跟踪系统是空间激光通信系统的关键技术，是通信链路建立的前提。而视轴初始指向作为捕获系统中的第一步，是能否成功捕获、捕获概率大小以及捕获时间长短的决定性因素。为了快速建立空间激光通信链路，通过分析初始指向技术的组成与工作原理，建立了初始指向系统模型。提出了初始指向系统的视轴标校方法，且根据误差分析方法得到了系统指向精度。实验结果表明，该指向系统可以快速地建立空间激光通信链路，且指向精度高，验证了该指向系统的正确性与可行性。 |

| Acqusition, pointing and tracking is the key technology in space laser communication system. And it is the premise of the communication link establishment. The initial alignment as the first step in the acquisition system is the decisive factor for the success of the acquisition, the acquisition probability, and the length of time. To quickly establish the space laser communication link, the initial alignment system model is established by analyzing the composition and working principle of the initial alignment technique. Calibration method on initial alignment line of sight is proposed, and the system alignment accuracy is obtained according to error analysis method. The experimental results show that the alignment system can quickly establish the space laser communication link, and it has high alignment accuracy, which verifies the correctness and feasibility of the alignment system. |
