【摘要】 地震数据经KL变换后,由于信号的连续性及形态的不同,其对应的主成分序列也不尽相同,从而使各种反射信号与噪声得到较好的分离。本文基于KL变换的基本原理,阐述了在海洋地震资料处理中应用本征滤波技术压制多次波、线性干扰和随机干扰的效果。实际地震资料处理结果表明,运用此方法压制海洋地震资料中的多次波和其他干扰波效果明显。更多还原

【Abstract】 After KL transformation, the continuity and form of the KL transformed seismic data is different from that of original seismic data, and the principal component sequence of the KL transformed seismic data is different from that of the original seismic data as well, as a result the several kinds of reflected signals and the noise can be separated very well. Based on basic principle of KL transformation, application of intrinsic filtering technique to suppress multiple, linear noise and random interference were introduced in this paper. Field seismic data processing results show that the multiples and other noise waves were suppressed very well by using this technique in marine seismic data processing.更多还原
