摘　　要： 随着航空飞行试验数据量的不断增加,原有IRIG106遥测系统已不能完全适应当前和未来的需求;同时随着网络技术的不断发展,遥测系统的网络化成为新的发展趋势;民用4G通信占用S波段遥测资源使得航空遥测寻找新的传输频段;为了充分利用和保护现有资源,并适应遥测的网络化发展,提出在现有S波段遥测基础上增加C波段网络数据传输功能,开展双波段遥测天线设计技术研究;在对天线结构进行合理设计的基础上,提出了一体化馈源设计方案;通过S波段振子与C波段振子的集成化设计,实现了C波段无线网数据与S波段串行数据流的共同传输,极大地提高了遥测数据传输速率,缓解了遥测频率资源紧张的现状;通过飞行试验验证,设计的双波段天线能够满足飞行试验大速率数据的传输需求。 With the increasing volume of aviation flight test data,the original IRIG106 telemetry system has not been fully adapted to current and future needs.At the same time with the continuous development of network technology,telemetry system network has become a new development trend.The fourth generation mobile communication occupies the S-band telemetry resources so that the aerial telemetry searches for new transmission bands.In order to make full use of and protect existing resources and adapt to the development of telemetry network,this paper proposes to increase the data transmission function of C-band network on the basis of existing S-band telemetry and carry out research on dual-band telemetry antenna design.Based on the properly design of antenna structure,the integrated feed design project is proposed.Through the integrated design of S-band and C-band dipoles,common transmission of C-band wireless network data and S-band telemetry data has been implemented.Telemetry data rate has been improved and the absence of telemetry frequency resource has been alleviated.Verified by flight tests,the design of dual band antenna can meet the transmission requirements of high rate data.
