综述了面向无人机(UAV)领域光无线通信(OWC)的主要研究进展,分别阐述了借助光无线技术在无人机与陆上终端间、无人机与无人机之间以及无人机与卫星之间,实现稳健、宽带通信链路的诸多研究进展与关键使能技术。重点阐述了不同无人机光无线链路配置下的链路建模、参数优化、实验测试。同时,也初步讨论了高速、高可靠无人机机载光无线通信技术在模块化实现、高空平台应用等方面的发展趋势。

In this paper, recent research progress of optical wireless communications in unmanned aerial vehicles (UAVs) was reviewed. By means of wireless optical technology, technical challenges and key enabling technologies were also surveyed for implementing robust and wideband communication links between UAV and satellite, UAV and UAV, and UAV and terrestrial terminals. The mechanisms and schemes of modeling, parameter optimization, and experimental testing under different UAV optical wireless link configurations were described in detail. Additionally, the key development trends of high-speed and high-reliability UAV-based wireless optical communication technology in modular implementation, high altitude platforms applications, and others were discussed.
