摘　　要：针对灾害发生导致的大面积通信网络中断区域内应急通信网络部署问题,提出一种多无人机协同飞行部署规划方案和多无人机协同飞行轨迹规划算法,通过未损毁基站构建连通链路,以提高空中临时基站群的网络覆盖能力,可得到多无人机基站协同飞行优化部署轨迹。仿真结果表明,所提出的多无人机协同飞行覆盖轨迹规划算法在提高无人机基站用户覆盖率的同时,可显著减小多无人机区域覆盖部署的移动时延,并减少了无人机资源配置数量。Aiming at the problem that emergency communication network deployment in areas where a large area of communication network is disconnected caused by disasters,the paper proposed a multi-UAV cooperative deploy-ment plan and a multi-UAV cooperative trajectory planning algorithm,and built connected links through undamaged base stations to improve the network coverage of temporary air stations,so that the optimized deployment trajectory for coordinated flight of multi-UAV base stations can be obtained.The simulation results show that the proposed multi-UAV cooperative coverage trajectory planning algorithm can increase the user coverage of UAV base stations,and sig-nificantly reduce the movement delay of multi-UAVs and the allocation number of UAV resource.
