摘要
基于强噪声的地震记录,先利用小波包分析对地震记录进行分解,然后再根据不同的信息的不同特征性进行去噪,然后再重构。用小波包变换去噪后的地震信号再利用K-L变化提取有效信号。经合成地震剖面处理试验证明,该方法能有效地提高地震记录的信噪比和分辨率。
Strong noise based on the seismic records, the first analysis of the use of wavelet packet decomposition of seismic records, and then, depending on the different characteristics of information to carry out a de--noising, and then reconstruction. Using wavelet packet transform to remove noise and then the seismic signal changes in the use of KL signal extraction. By synthetic seismic profile experiment proved that this method can effectively improve the seismic records of the signal to noise ratio and resolution.
