摘　　要：当前机动测控设备虽能基本满足低轨卫星的测控与数传需求,但难以满足高轨大容量卫星的高速数传需求。针对该问题提出一种分布式天线测控与通信系统,该系统采用多个小口径天线构成的分布式阵列,可突破单一天线口径限制,实现对高速数据传输信号的有效接收。论证分析了该系统的必要性与可行性,从宽带信号多天线合成技术、系统时频同步技术、系统实时处理技术3个方面对分布式天线测控与通信技术进行了阐述,并提出了相应的解决方案,为建设高轨大容量卫星的高速数传网络提供了理论与技术支撑。At present,the mobile TT&C equipment can basically meet the requirements of low-orbit satellites communication.However,it is difficult to meet the requirements of high speed data transmission of high-orbit and large-capacity satellites.The TT&C system based on distributed antennas is researched and the feasibility of this system is analyzed,which adopts a distributed array composed of multiple small-diameter antennas to break through the limitation of a single antenna aperture and realize the effective reception of high-speed data transmission signals.The necessity and feasibility of the system are demonstrated and analyzed and the distributed antenna TT&C and communication technology is elaborated from three aspects,namely,broadband signal multi-antenna synthesis technology,system time-frequency synchronization technologyand system real-time processing technology.Corresponding solutions are proposed,which provides theoretical and technological support for the construction of high-speed data transmission network of high-orbit and large-capacity satellites.
