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Solving the static correction problems under complex near - surface conditions is a systematic engineering. first, careful field weathering investigation must be done, then we have to take full advantages of refraction first - break information and field weathering investigation information to compute field static correction and large residual static corrections with various refraction first - break statics methods, finally, reflection statics methods are used iteratively to solve the residual statics problems. to solve serious static correction problems in complex near - surface areas of western china, different refraction first - break statics methods are studied in this thesis. the main study contents are as follows : 1 ) the propagation features of refraction for horizontal layered and dip media are studied firstly, it lays a good theoretical foundation for later statics method studies
