针对激光通信组网对多目标捕获和跟踪的需求，提出了一种基于旋转抛物面的多反射镜拼接式新型捕跟机构。首先探讨了激光通信组网的工作原理和过程，完成了捕跟机构设计，建立了反射镜驱动机构扫描捕获和跟踪两个阶段的运动学模型，并对模型进行了仿真，在此基础上，构建了室内原理试验系统，对捕跟机构的跟踪精度和交接效果进行了测试。测试结果表明：系统最终跟踪精度为22.14μrad （1σ），交接过程中通信无误码，因此，本捕跟机构能够实现方位角范围360°、俯仰角范围30°一点对多点同时激光通信的要求。

For multiple target acquisition and tracking in laser communication networking,one conceive of optical anten-na based on paraboloid of revolution is put forward in this article. The working principle and process of laser communi-cation network were discussed,and the acquisition and tracking mechanism were designed,and the kinematics model of acquisition and tracking phase is established, the acquisition model and tracking model were analysis and simulated by matlab, which can provide theory evidence for control system. On the basis of above all, the principle test system were built, and the acquisition and tracking precision and transition effect was tested. The test results show that, The tracking precision of the system is 22.14μrad (1σ), and no communication error in the transition process. The request of multi-point laser communication at the same time can be achieved by this mechanism,and the range of communica-tion object is 360 ° in azimuth range,30 ° in pitching range.
