摘要
介绍了f-x-y域预测滤波方法,提出了基于奇异值分解的三维f-x-y域预测滤波方法。该去噪方法是在奇异值分解滤波的基础上进行f-x-y域预测滤波,从而实现频率空间的预测滤波。2种滤波方法详细的对比研究及理论模型试算的结果表明,该方法较f-x-y域预测滤波能更好地提高地震资料的信噪比,并有更高的保真度。
We introduce the prediction filtering method inf-x-y domain. The prediction filtering method using singular value decomposition inf-x-y domain has been put forward in this paper. Thef-x-y prediction filtering can be applied after the SVD filtering. Thus the prediction filtering is carried out inf-x-y domain. Finally we compare the routine prediction filtering method with the prediction filtering method using singular value decomposition. The theoretical ＇modeling results show that the method can more effectively increase the signal/noise ratio than the routine method. And it can maintain the continuity of effective events.
