摘　　要：针对无人机集群编队协同飞行时,机载设备通过自组网数据链传输测试数据时引起的时延问题,为测试数据标记精确的时间信息,对于分析测试数据的时效性具有重要意义。同时,通过捕获和分析数据包,能够得到数据链的传输时延、流量和丢包率等性能指标。提出了一种空地数据链时延测试系统设计方案,主要由发送装置、接收装置和网络信息监测系统3部分构成。该测试系统能够测量无人机集群的航迹信息,并分析数据链的传输时延、流量和丢包率等指标。During collaborative flight test of UAV cluster formation,delay issues caused by ad hoc network through which airborne equipment transmit test data.Marking accurate time information for test data is of great significance for analyzing its timeliness.By capturing and analyzing data packets simultaneously,performance indicators such as transmission delay,traffic and packet loss rate of the data link can be obtained.This article proposes a design scheme for an air-ground data link delay testing system,which mainly consists of three parts:a sending device,a receiving device and a network information monitoring system.The system can measure the trajectory information of the UAV cluster,and analyze the transmission delay,traffic and packet loss rate of its data link.
