讨论了二维AR模型以及三维叠后f－x,y域预测随机噪声衰减技术；推导了沿不同空间方向预测的二维AR预测模型及其系数之间的关系；实现了基于同样原理之下的地震数据体边缘处的预测。实际资料处理结果表明，这种处理方法在保持信号原有特征方面要优于f-x,y方法。
The two-dimensional AR model and the three-dimensional post-stack f-x, y-domain prediction of random noise attenuation are discussed. The relationship between the two-dimensional AR prediction models and their coefficients predicted in different spatial directions is deduced. Based on the same principle Prediction of seismic data body edge. The actual data processing results show that this method is superior to the f-x, y method in maintaining the original characteristics of the signal.
