  5. 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

    本文根據小波分析的基本原理,對原子鐘信號進行多解析度分解,將分解后的小波變換系數進行加權平均,得到不同小波尺度綜合原子時的加權平均小波變換系數,然後由小波變換的重構條件,反演綜合時間尺度.由於對原子鐘信號進行了小波分解,利用不同尺度的小波變換系數的小波方差進行加權平均,這樣既考慮不同原子鐘在穩定性方面的差異,又顧及同一臺原子鐘在不同小波尺度的變化特性.最後根據陜西天文臺國家授時中心的實測數據對這種方法進行了檢驗.表明這是一種全新的多解析度綜合方法,這種方法比較簡單而切實可行,它能提取各個原子鐘的共同特性,多解析度綜合時間尺度的平穩性明顯優于其他方法
