基于C波段无线网的模拟飞行视频遥测传输技术研究

摘要

To solve the current contradiction between telemetry frequency resource shortage and increasing flight test de⁃mand,the C⁃band wireless network technology is researched. On the basis of comparing the characteristics of IRIG 106 Teleme⁃try Standard and iNET Telemetry Network Standard,the simulation flight video telemetry transmission technology scheme based on C⁃band wireless network is proposed according to iNET Telemetry Network Standard to realize the two⁃way transmission in C⁃band. The key devices of the network transceiver in C⁃band,LNA and power amplifier are increased to realize the two⁃way transmission of C⁃band network data,which can greatly improve the transmission rate of telemetry data,and alleviate the cur⁃rent situation of the telemetry frequency resource shortage.%针对目前遥测频率资源紧张与飞行试验需求不断增长之间的矛盾，对C波段无线网技术进行研究。在比较IRIG 106遥测标准和iNET遥测网络标准的各自特点的基础上，根据iNET遥测网络标准，提出基于C波段无线网的模拟飞行视频遥测传输技术方案，实现C波段双向传输功能。通过增加C波段网络收/发器、LNA和功放等关键设备，实现C波段网络数据的双向传输，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。
