VHF天线阵列时频系统构建及授时策略研究
Construction of time-frequency system for VHF-band antenna array and its time service strategy research
摘要
Abstract
A time-frequency system architecture of the VHF-band antenna array,is introduced. The generation of standard 10 MHz signal and clock driving signal needed by the sampler,and a scheme of time comparison between two sampling and con-trol computers based on different GPS network time services,which can ensure that the two computers receiving the sampling da-ta have the same time and guarantee that the time scale of the storage data is accurate,are presented also in this paper. The study on the time service strategy is based on the LabVIEW graphical programming platform. The time comparison software was compiled to obtain system time of the two computers needing timing. The time length of the time deviation existing in the two computers is determined with the analysis and contract. The experimental results show that the scheme can automatically cali-brate the system time of the computers in the LAN,and its deviation is less than 0.1 s.关键词
