波动方程相移偏移法

本文讨论五个问题:(一) 相位移方法原理;(二) 相位移在计算机上实现的步骤;(三) 相位移法怎样与二维滤波相结合;(四) 模型试算;(五)几点讨论。本文对原方法的主要改进点是把相位移法与频率域二维滤波结合在一起进行运算。

Wave equation phase displacement migration

Five questions are discussed in this paper;1)The principle of phase displacement method; 2)The steps of performing phase displacement on a computer;3)How to combine phase displacement method with twodirmensional filtering;4)Experimental calculating on model;5)Several points far discussion.Improvement to the old method formulated in this paper mainly lies in the combination of phase displacement method with froquency two-dimerlsional.filtering in making operation.
