提出一种基于非局部平均算法的随机干扰压制方法,将它用于提高地震记录的信噪比,并与使用自回归模型的f-x反褶积结果进行比较,表明这种方法能有效压制随机干扰。
A non-local averaging algorithm based on random interference suppression is proposed, which is used to improve the signal-to-noise ratio of seismic records. Compared with the results of fx deconvolution using autoregressive models, it shows that this method can effectively suppress random interference .
