| 摘 要： | 针对常规F-X域预测方法的效果严重依赖于原始地震数据信噪比的缺点,本文提出一种优势频带算子外推噪声衰减方法。这种方法充分利用了相邻频带预测算子之间的关系,用高信噪比频带的预测算子去预测低信噪比频带的预测算子,使低信噪比频带预测算子具有可靠精度,从而保护了低信噪比频带中的有效高频信号。

| Abstract: | Usually f-x prediction filtering seriously depends on S/N of original seismic data.A predominant frequency-band operator extrapolation for noise attenuation improvement in f-x domain is proposed in the work.In order to get dependable prediction operators of the lower S/N frequency band,the method,utilizing the relation of close frequency band prediction operators,predicts the lower S/N frequency band by prediction operators of high S/N frequency band.In this instance,the precision of the prediction operator... |
