摘要
本文介绍了1985年国际搬钟时间同步实验和1987年国内搬钟时间同步实验中使用双混频时差(DMTD)测量技术的结果。实验结果表明:DMTD测量技术在搬钟时间同步实验中,对于确定钟速和同步精度以及严密监视钟的相位、频率跳变等方面是很有用的。它与秒脉冲(1PPS)时差测量技术可以同时使用和相互补充。
This paper describes the results of the dual mixer time difference (DMTD) measurement technique which were used in the time synchronous experiment via transporting clocks between continents in 1985 and at home in 1987. The experimental results have shown: DMTD measurement technique is very useful in determining the clock rates and the time synchronous precision, as well as in monitoring the phase and frequency jumps, and so on. DMTD and 1 PPS time difference measurement technique can be simultaneously used, and complemented each other.
