【摘要】 时间尺度是通过综合众多精密时钟得到的。时间尺度的计算目前主要采用类ALGOS算法 ,这类算法的缺点是权值没有准确反映精密时钟噪声参数以及不能使五种噪声分量同时达到优化综合和不能形成实时的时间尺度。从精密时钟综合的优化算法原理出发 ,探讨了精密时钟噪声参数的估计、精密时钟噪声中噪声分量的分解等问题的解决方法 ,并由此提出了较优化的时间尺度算法 (精密时钟综合算法 ) ,还提出了对现有算法的改进意见。更多还原

【Abstract】 Time scale is generated by synthesizing a number of precision clocks. ALGOS algorithm or ALGOS-like algorithm is usually adopted in computation of time scale. The defects of this algorithm are as follows: (1) the adopted weight can not reflect the noise level, (2) the algorithm can optimally synthesize the noises for one component,but not for all components, (3) the algorithm cannot generate time scale in real time. Based on the principle of optimum algorithm for precision clock synthesis, the following aspects are studied: (1) to estimate the noise coefficients for precision clock, (2) to separate the noise components in precision clock, (3) to obtain the time scale in real time. At last ,a improved algorithm for time scale (synthesi algorithm of precision clock) is presented and the suggestion to improve the existing algorithm is also made in this paper.更多还原
