摘要
首先讨论了K-L变换在地震图象处理中应用的基本原理,然后提出对相干性较差的噪声能量,可以通过在K-L域中的压制。有效突出原地震图象中相干性较好的有用的特征信息。文中给出了具体实现该方法的步骤,并讨论了关键性参数的选择。所给出的模型试算结果表明了该方法的良好效果。
The application of K-L transform in seismic image processing is discussed. After the fundamental principle discussed, restrining the energy of non-coherent noise in K-L domain can enhance effictive characteristic coherent information in seismic image is demonstrated. The effect of the methods is demonstrated by the results which is obtained by caculating methimatic models.
