• Based on the basic principle of wavelet analysis , multi - resolution analysis of signal in atomic clock is made . the coefficients of wavelet transform for synthesis atomic time , which are weighed and averaged at different wavelet scales , are obtained . then according to reconstruction theorem , multi - resolution synthesis time scale can be reconstructed . since the signal of atomic clock has been analysed by multi - resolution , we can use wavelet variance at different scales to weight and average the coefficients . thus either the difference in stability of different clock or the varying characteristic of the same clock at the different scale are all considered . finaly , this method is checked by the measured data from national timing serve center of shaanxi astronomy observatory . it confirmed that this technique , which is simple and practicable , is a new method of multi - resolution . from this method , the common characteristic of different clocks can be extracted . the stability of multi - resolution synthesis atomic time scale is obviously superior to that of other methods
  本文根据小波分析的基本原理，对原子钟信号进行多分辨率分解，将分解后的小波变换系数进行加权平均，得到不同小波尺度综合原子时的加权平均小波变换系数，然后由小波变换的重构条件，反演综合时间尺度.由于对原子钟信号进行了小波分解，利用不同尺度的小波变换系数的小波方差进行加权平均，这样既考虑不同原子钟在稳定性方面的差异，又顾及同一台原子钟在不同小波尺度的变化特性.最后根据陕西天文台国家授时中心的实测数据对这种方法进行了检验.表明这是一种全新的多分辨率综合方法，这种方法比较简单而切实可行，它能提取各个原子钟的共同特性，多分辨率综合时间尺度的平稳性明显优于其他方法
