• To this paper we were carried tentatively on spectrum whitening in prestack , and each section after division scale is processed with spectrum whitening , particularly the composition of high frequency is raised apparently , the signal - noise ratio of high frequency raise . the resolution of whole section is better than stack
  本文还尝试性地在叠前进行谱白化处理，对分尺度后的各个记录分别进行谱白化，尤其是高频成分提高得很明显，有效地提高了高频信噪比，整个剖面的分辨率明显增强。
• 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础上，在分频叠加方面做了进一步的研究。首先对地震记录进行剩余时差校正，校齐同相轴，为同相叠加做好基础工作；然后对地震记录用小波变换的方法进行分尺度处理；对各个尺度分别做谱白化，对于高、低频段需要做频带延拓，中间频段仅提升频谱值；对于几种信噪比定量估计的方法进行了深入的研究，并且总结了它们的优缺点以及适用范围；对谱白化后的地震记录用信噪比估计值作为加权系数进行加权叠加；对于各尺度的叠加剖面也进行信噪比估计，对于信噪比大的尺度给予大的加权系数，反之，信噪比值小的尺度给予小的加权系数，对各尺度叠加剖面进行加权重构。
