一种无人机双模宽带测控链路设计

针对传统无人机通信链路模式单一、通信带宽与设备简化相互制约、设备可替换性差等缺点，基于频分双工和时分多址通信体制、软件无线电技术、双天线自适应抗遮挡技术，设计了一套可用于直通模式和中继模式的宽带双模测控链路。该双模测控链路解决了传统机载设备必须换装才可切换飞机模式的难题，同时具有集成度高、可靠性高、小型化、通用性强等特点，适应测控链路小型化通用化的发展趋势。

Design of a Dual-mode Wideband TT&C Link for UAVs

For the shortcomings of traditional unmanned aerial vehicle(UAV) communication link,such as single mode,contradiction between communication bandwidth and equipment simplification,and poor equipment replacibility,a wideband dual-mode telemetry,tracking and command(TT&C) link for both pass-through and trunk modes is designed based on frequency division duplex(FDD) and time division multiple access(TDMA) communication system,software radio technology and dual antenna adaptive anti-occlusion technology.The dual-mode TT&C link solves the problem that the traditional airborne equipment must be replaced before the aircraft mode can be switched,and has the characteristics of high integration,miniaturization and versatility,and suites the development trend of miniaturization of TT&C links.
