针对传统频率信号处理仅把相位处理局限于相同频率标称值的情况，基于相位群同步和群连续的原理，使得相位处理适合于复杂频率信号之间，包括取样时间间隔(相位差)测量、处理和锁相控制等方法来改善原子钟的系统结构。该方法与传统的频率归一化及相位处理的方法相比，在简化系统的频率变化线路的情况下，通过简单的相位群同步的锁相控制，得到的原子钟输出信号有好的准确度和长期稳定度指标，以及优良的短期稳定度和相位噪声指标。

The atomic clock frequency signal link is the most important technology of the atomic frequency standard.This is because of the great difference in frequency between the atomic energy level transition signal and the output signal of the atomic clock.The basic method for the traditional frequency signal processing in phase is limited to the same frequency nominal values.The paper is based on the principle of continuous phase group synchronization and cluster,which makes the phase processing suitable for complex frequency signals.The clock system structure is improved using the methods of the sampling time interval (phase difference) measuring, processing and phase-locked control. Compared with the traditional frequency normalization method,the system frequency change circuit is simplified.By a simple phase lock control of group synchronization,the atomic clock output signal has a good degree of accuracy,a long term stability index,excellent short-term stability and phase noise performance.
