摘　　要：无人机通常以集群组网的方式进行协作传输,其凭借成本低廉、部署灵活等特点,在军事领域得到了广泛应用。由于无线通信的广播特性及无人机视距传输的特点,无人机群容易受到恶意干扰攻击。同时,由于无线频谱资源的稀缺性,无人机群需要共享有限的频谱资源以提升频谱效率,从而需要面对内部节点间的互扰问题,因此形成了干扰环境下无人机群最大化集群和速率的优化问题。为了提高干扰环境下无人机群数据传输的有效性和可靠性,提出了一种基于联盟形成博弈的分布式协同频谱决策方法,以应对外部的恶意干扰威胁及无人机群内部的互扰问题,进而实现干扰威胁下无人机群动态、高效、智能的频谱决策。借助势能博弈理论证明了所提抗干扰联盟形成博弈可以实现稳定的联盟分组,并可得到纳什均衡解。Unmanned aerial vehicles(UAVs)are widely used in the military field due to their low cost and flexible deployment,which are usually carried out in the form of cluster network for cooperative transmission.Because of the broadcasting nature of wireless transmission and the line-of-sight transmission characteristics,UAV swarm is vulnerable to malicious jamming attacks.Moreover,due to the scarcity of spectrum resources,the UAV swarm needs to share the limited spectrum resources,which will introduce severe co-channel interference.Therefore,the problem of cooperative spectrum sharing among UAV swarm is not only threatened by the malicious jamming,but also limited by the mutual interference among UAVs.Specifically,an optimization problem is formulated to maximize the sum rate of UAV swarms in the jamming environment.To improve the effectiveness and reliability of the UAVs’transmission,this paper proposes a distributed spectrum decision-making method based on the coalition formation game,to deal with the external jamming threats and the internal mutual interference.Thus,the dynamic,efficient and intelligent spectrum control can be realized for the UAV swarm under the jamming threat.Meanwhile,with the help of potential game,the proposed anti-jamming coalition formation game turns out to be able to form the stable alliance grouping,and achieve the Nash equilibrium.
