摘　　要：对两架无人机(UAV)构建的通信中继链路的最优链路代价问题进行了研究。中继UAV要求以尽量小的通信代价维持中继链路,而侦察UAV需要通信代价较大的中继链路,以支持大范围侦察任务。因此,中继UAV和侦察UAV对通信中继链路的代价需求是一个微分对策问题。基于极大极小对策对这一问题进行建模求解,提出基于几何法的UAV导引律,进行UAV导引律设计时假设对手都是处于静止状态的,得到了可行的次优解。仿真试验表明了导引律设计方案的可行性,中继UAV和侦察UAV在相应的控制下,都能按照各自对通信链路代价的需求向目标运动。Research of optimizing the cost of communication relay link constructed by two UAVs is made in this paper. Relay UAV requires to maintain a small relay link with minor communication cost, and reconnaissance UAV needs a larger communication link cost in order to support a wide range reconnaissance mission. Therefore, the relay UAV and reconnaissance UAV demanding for communications relay link is a differential game problem. This paper based on model and solve this issue based on Minimax principle, proposed UAV guidance law based on geometric method and get a feasible suboptimal solution, when carried out UAV guidance rate, assuming that the opponents are in a quiescent state. Simulation results show the feasibility of the design guide rate, the relay UAV and reconnaissance UAV under the corresponding control can follow the movement of each control objective consideration of the communication link.
