C波段无线网与S波段遥测天线共用技术研究

Research on antenna sharing technology for C-band wireless network and S-band telemetry

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波段无线网与S波段遥测天线共用技术进行研究。根据实际使用需求,要求在保持原有S波段功能的基础上,增加C波段双向传输功能。因此在对天线结构进行合理设计的基础上,给出了一体化馈源设计方案,通过增加C波段无线网络收/发器等关键设备,实现C波段无线网数据与S波段遥测数据的共同传输,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。

The research on antenna sharing technology for C-band wireless network and S-band telemetry was done because of the conflict between the absence of telemetry frequency resource and the increasing demand of flight test. According to the ac-tual application requirements,C-band two-way transmission function needs to be enhanced while maintaining the original func-tion of S-band. Base on the rational design of antenna structure,the integrated feed source design project is proposed. Common transmission of C-band wireless network data and S-band telemetry data has been implemented by adding some critical equip-ments such as C-band wireless network transceiver,power amplifier,etc. Telemetry data rate was improved immensely and the absence of telemetry frequency resource was alleviated.
