通信网络是保证无人机在协同搜索时获取更多的战场信息，发挥协同作战优势的基础。主要研究多无人机完成通信中继任务过程中的搜索路径规划和通信性能优化问题。搜索路径规划的目的是确定未知地面移动人员具体方位并对其组网，以便无人机执行中继任务；而通信优化问题则是针对无人机中继过程中可能出现的通信中断、失真等问题，分析通信网络信息传输的路由选择，选取通信延时为性能指标，通过改变无人机的路径选择来提高通信网络的性能。仿真结果表明了本文实现通信中继和通信网性能提高的有效性。

Communication network is the foundation for the multiple unmanned aerial vehicles (UAVs)to get more information and to exert the advantage of cooperative campaign when they are cooperating in communi-cation relay tasks.This paper mainly focuses on the problem of search path planning and communication optimi-zing during the process of cooperative relay.The path planning is to find the location of moving crew on the ground and build up a communication network for UAVs to perform the relay task;the communication optimi-zing is to solve the problem of communication intermit and distortion during the process of relay,analyze the in-formation routing of the network,choose communication delay as the performance index,and change the loca-tion of UAVs to improve network performance.Simulation results indicate that during the search task this ap-proach can improve the performance of the network.
