    本文首先從所收集的級在5級以上2861條面記錄中挑選形好、記錄完整的資料進行預處理,計算其大園路徑,從中挑選出位於同一地大園路徑上的雙臺地記錄約284對,然後計算出前向方位角差,其差在5范圍以內的雙臺地記錄約260對,量后對這些記錄進一步優化,選出223對對中國大陸地區覆蓋比較好的面記錄。
  4. Doing the further research on the division frequency stack on the foundation of study of predecessor, at first the residual moveout correction is done to the seismic record, make the phase axle regularity, doing foundation for the same phase stack ; then carried on division scale processing by wavelet transform ; spectrum whitening is done to each scale, the high and low frequency band need to do prolongs, the middle frequency bands only increase the value of the frequency spectrum ; several kinds of methods that estimate the value of signal - noise ratio has been studied further, and summarize their advantage and disadvantage as well as the scope of application ; the seismic record after spectrum whitening is stacked by weighting with the value of the signal - noise ratio ; then estimate the value of signal - noise ratio which is each scale section after stacking, the scale that the signal - noise ratio is big is assigned big weighting, otherwise, the scale that signal - noise ratio value is small is assigned small weight ing, and carried on weighted reconstruct to each scale section

    本文在前人研究的基礎上,在分頻疊加方面做了進一步的研究。首先對地記錄進行剩時差校正,校齊同相軸,為同相疊加做好基礎工作;然後對地記錄用小變換的方法進行分尺度處理;對各個尺度分別做譜白化,對于高、低頻段需要做頻帶延拓,中間頻段僅提升頻譜值;對于幾種信噪比定量估計的方法進行了深入的研究,並且總結了它們的優缺點以及適用范圍;對譜白化后的地記錄用信噪比估計值作為加權系數進行加權疊加;對于各尺度的疊加剖面也進行信噪比估計,對于信噪比大的尺度給予大的加權系數,反之,信噪比值小的尺度給予小的加權系數,對各尺度疊加剖面進行加權重構。
