自适应倾斜面元法（ADA）──一种改进的叠加算法

ADAPTIVE-DIP-AREA(ADA) METHOD──A IMPROVED CMP METHOD

自适应倾斜面无法（Ａｄａｐｔｉｖｅ—Ｄｉｐ—Ａｒｅａ）是一种改进的水平叠加处理方法，是在不增加野外工作量，不增加偏移距的情况下，利用相邻点的信息来估算某一点的反射波，从而等效地增加叠加次数，提高信噪比。它对静校正与动校正的误差应用自适应的方法进行补偿。同时，采用非线性处理方法，避免了因均匀层、倾斜层的假设可能对断点、尖灭点产生的模糊作用。

he Adaptive-Dip-Area (ADA) method is a improved CMP method. It can be used toestimate the reflection wave of a given point with the renection waves of the neighboring points, withoutincreasing field work and migration distance. So the stacking fold and the S/N ratio are raised. The error ofthe statics and NMO corrections can be compensated by ADA method.And the possible vagueness of thefault points and pinchout points can be avoided by using the nonlinear method.
