利用平衡正交多小波和维纳滤波方法提高地震记录的信噪比

Improving the S/N ratio of seismic record by balanced orthogonal multiwavelet and Wiener filter method

结合平衡正交多小波变换和维纳滤波方法对地震剖面进行去噪处理。用两个多小波变换实现在小波域上的维纳滤波,以提高地震剖面的信噪比,试验结果表明,该方法优于单纯的多小波去噪方法。

Denosing process of seismic record is discussed by using balanced orthogonal multiwavelet transform and Wiener filter. Wiener filter in multiwavelet domain can be realized for seismic denoising by using two balanced orthogonal multiwavelet transform. Experimental results show the proposed method outperforms multiwavelet method.
