摘要
美国的"太空篱笆"系统采用了全数字相控阵体制,阵元规模庞大,其超大规模高速数据的稳定传输是系统设计的难点。在分析"太空篱笆"系统特点的基础上,提出了数字光纤分布式大规模高速数据传输架构,并介绍了数据传输架构组成及特点,对其中关键的稳定性设计方法进行了描述与分析。对整个数据传输架构进行了测试,结果表明数据传输稳定、可靠,有效保证了数据同步及异常自恢复。
The US space fence system is based on all digital phased array. Because of the large scale of antenna elements,the sta-ble transmission of large-scale high-speed data is the difficulty in the design. Based on the analysis of space fence system characteris-tics,this paper puts forward a large-scale high-speed data transmission architecture based on digital fiber optic. The composition and characteristics are introduced in detail. The key design method of the stability is analyzed. The data transmission architecture is tested at last. The results show that the data transmission is stable and reliable. The data synchronization and automatic recovery function are guaranteed efficiently,and the desired design objectives are reached.
