摘　　要：建立机载无线紫外光非直视通信模型与无人机覆盖模型,引入三种相对虚拟力,提出一种基于相对距离的改进虚拟力覆盖算法控制无人机移动,仿真分析了不同场景下算法的性能以及紫外光通信角度对算法覆盖率影响。仿真结果表明,所提算法减小了无效覆盖以及重叠覆盖,相比随机部署算法、贪婪虚拟力算法和移动部署算法的覆盖率分别提高了18.33%,3.15%和1.83%,并减小了无人机的能量消耗。Due to the complex and ever-changing battlefield environment,fixed communication equipment is often damaged in combat zones,resulting in a massive breakdown of communication and thus affecting combat effectiveness.Using the advantages of the UAV's strong survivability and wide coverage,it is possible to carry communication equipment as an UAV aerial base station to provide communication services to ground users.The single UAV base station has disadvantages such as weak resistance to destruction and limited coverage and power,so the choice is made for multiple UAV base stations to work together to provide communication services to a large area and multiple users.In complex military environments such as strong electromagnetic interference and“electromagnetic silence”,traditional wireless communication methods have poor confidentiality and are susceptible to interference and eavesdropping by the enemy,while wired communication requires cables to be laid in advance and is not easily used in complex,dynamic and changing military environments.Wireless ultraviolet communication,based on its all-round and terrain adaptable working characteristics,overcomes the shortcomings of wired communication requiring cable laying,as well as the strong absorption of ultraviolet light by the atmosphere,making ultraviolet communication with a low location detection rate performance,compared to wireless communication methods such as radio frequency communication and infrared light communication has better area covert transmission.It can be used as an independent network unit to access the modern communication network architecture,and can also be interconnected with wireless and wired communication networks to achieve resource information sharing.By establishing an airborne wireless UV non-direct vision communication model with the UAV coverage model,the coverage of the UAV is maximized while satisfying the premise of path loss.In order to ensure the quality of communication services for ground users,the received power of ground user
