摘要：

由于超过一定距离的时间和频率的比对方法与时间和频率的传递技术密切相关。尤其自本世纪初无线电问世以来,用无线电通信进行传递和比对方法的产生,已代替了有线电报发明以来所使用的陈旧技术,所以无线电信号用于时间频率传递以及进行远距离钟和频标的比对是使用最多的一种方法。本文主要介绍了无线电信号的时间频率传递系统和比对方法中罗兰C系统的设备结构,技术指标,信号特性等。

Abstract: Because the comparing method of time and frequency which exceed certain Range has close relationship with the transport of time and frequency, the method of using radio signal to transport time and frequency, to compare range-clock with frequency-mark has became the most popular way.All the old techniques have been taken place by the new method which uses radio signal to transport and compare.This article mainly discuss the transport system of time and frequency, comparing method of radio signal, the structure, index and signal characteristic of the LORAN-C system.

Keywords: LORAN-C; Time; Frequency
