| 摘 要： | 为了更加准确地求取滤波算子,同时也为了得到更好的预测滤波结果,本文提出了三维空变f-x-y域预测滤波方法。该去噪方法的实现原理是在目标函数中引入了预测算子的先验信息,将各个时窗预测算子的求取有机地联系起来,从而实现频率空间的预测滤波。理论模型试算表明,该方法较f-x-y域预测滤波能更好的提高地震资料的信嗓比,保持地震同相轴的连续性。 |

| Abstract: | In order to find more accurate the filtering operators and better prediction filtering results,the prediction filtering meth-ed using space varying in f-x-y domain has been put forward in this paper.The transcendental information about predicting operator is introduced into the function in the method.To obtain the predicting operators is no longer independent problem,but related problem. Thus the prediction filtering is carried out in f-x-y domain.With this technique,we can not only increase the signal/noise ratio but al-so maintain the continuity of effective events.The validity of this technique has been proved by applying it to the theoretical modeling. |
