摘要
针对无网络环境中的大容量通信基站快速部署的应用需求,研究基于无人机机载激光传输技术实现升空基站与地面网络宽带互联。为克服搭载平台随机运动特性与强振动环境,采用自动瞄准与多级协同稳定跟踪技术实现激光传输天线快速扫描捕获和精确对准,满足光通信链路与升空基站的快速灵活接入需求。并针对小型无人机负载能力有限的特征,采用收发同轴设计与非对称光学系统,降低设备体积重量。然后,通过飞行试验验证快速部署升空基站无人机机载激光传输技术方案的可行性。
In order to rapidly deploy large capacity communication base station at no network area,the interconnection between fast lift air base station and ground broadband network is realized by unmanned aerial vehicle airborne laser transmission technology to meet the application. For the purpose of overcoming the random move and strong shock airborne platform environment, the technology such as automatic pointing and multi-stage collaborative stable track is designed for fast scanning acquisition and precise alignment between the laser transmission optical antennas, by this way the laser communication link can rapidly and flexibly access to air base station. Asymmetric optical system with coaxial transceiver is designed to reduce the volume and weight of optical antennas, which can meet demand of small-size unmanned aerial vehicle restricted load capacity. Finally, the feasibility of unmanned aerial vehicle airborne laser transmission technology for rapidly deploy air base station has been verified by flight tests.
