三维地震数据的同一共中心点道集是由不同方位角的地震道组成的。当地下地层倾斜时，共中心点道集的反射同相轴就存在方位角时差。本文根据方位角时差校正（ＡＭＯ）的基本原理，从ｆ－ｋ域的正、逆ＤＭＯ出发，通过稳相法得到积分法ＡＭＯ脉冲响应的时间、振幅因子公式。把ＡＭＯ应用于一束实际三维地震数据处理，经ＡＭＯ处理后的剖面绕射波和断面反射波得到了加强，其效果是令人满意的。
The same concentric point gathers of 3D seismic data consist of seismic traces of different azimuths. When the local subterranean strata tilt, there is azimuthal jet lag in the reflection axis of the common center point gathers. Based on the basic principle of azimuthal time difference correction (AMO), this paper starts from the forward and inverse DMO of f-k domain, and obtains the formula of time and amplitude factor of AMO impulse response by integral method. The application of AMO to a bunch of actual 3D seismic data processing, after the AMO processed profile diffraction and cross-section reflected waves has been strengthened, the effect is satisfactory.
