The method is fast and thus appropriate for real - time applications since no iterative operation is involved
提出的算法在寻找最优阈值的过程中无需迭代计算，因此速度快，适合于实时应用。
In view of characteristics of seismic data of gobi - sand dune areas , this paper , through various data - processing means such as quality control , high - pass filltering , dip angle filltering , field static correction , surface consistency deconvolution , precise velocity analysis , denoising before stack , multiple iterative operation of residual static correction , denoising after stack and modification after shift , has raised the data quality of seismic profiles in low signal - to - noise ratio areas and managed to form the seismic data - processing technique for such complex areas as gobi , foreland and dune
摘要针对戈壁、沙丘地区地震资料的特点，通过对原始资料进行质量控制、高通滤波、倾角滤波、野外静校正、地表一致性反褶积、精细速度分析、叠前去噪、剩馀静校正多次迭代、叠后去噪和偏后修饰等处理，提高了低信噪比地区地震剖面的资料质量，摸索出了一套戈壁、山前、沙丘等复杂地区地震资料处理技术。
