测控通信系统射频资源可重组技术

摘要

Resources reconstruction is the development direction of TT&C communication system for aerial vehicles. Based on the TT&C terminal reconstruction in the intermediate frequency and analysis of the archi-tecture of the RF resources reconstruction,it is concluded that the performance of RF switching network and RF remote transmission directly affects the feasibility of RF resources reconstruction. This paper proposes a feasible TT&C architecture of the entire system reconstruction. According to the architecture,micro-optoelec-tronic RF switching network and the RF optical transmission technology are adopted to realize large-scale ex-change and remote transmission of RF signal, and then the entire system reconstruction in combination with the TT&C terminal reconstruction. The system performance is analyzed. The idea proposed by this paper can be used for reference in the entire system resources reconstruction of TT&C communication system.%测控通信系统的资源重组将是飞行器测控通信系统的发展方向。在中频实现测控终端重组的基础上，通过对射频重组构架的分析，得出了射频交换网络的性能和射频远距离传输的性能直接影响射频重组的可行性，提出了一种可行的全系统资源重组的测控体系构架，即采用微光电子射频交换网络与射频光波传输技术实现射频信号大规模交换及远距离传输，再结合中频重组以实现全系统资源重组，并对相关性能进行了分析。所提出的设计思路可供测控通信系统实现全体系的资源重组借鉴及参考。
