摘　　要：为解决基于毫米波无人机通信信号在非视距(NLoS)环境中衰减大的问题,提出优化用户视距覆盖(LSCO)方法.根据用户提供视距覆盖和最大化无人机(UAV)与用户间的信噪比(SNR),建立关于UAV位置和取向的目标问题;然后将该问题转化为整数线性规划问题,利用基于几何法的贪婪算法求解.仿真结果表明,相比基准方法,本文提出的LSCO方法能满足用户视距(LoS)覆盖要求,提高了用户与无人机间的信噪比值.In order to solve the problem of significant millimeter-wave-based UAV communication signal of attenuation in the non-line-of-sight environment,this paper proposes a Line-of-Sight Coverage Optimization(LSCO)algorithm for users.Firstly,according to the user-provided line-of-sight coverage and the maximized signal-to-noise ratio(SNR)between UAVs and users are established the target questions about the UAVs’position and orientation.And then,the problem is transformed into integer linear programming problem and solved by using greedy algorithm based on geometric method.The simulation results show that compared with the benchmark treatment,the proposed LSCO method can meet the requirements of line-of-sight(LoS)coverage,and improve the SNR value between users and UAVs.
