| 摘 要： | 本文讨论波场的一种转换,称为消除倾角影响变换（DART）,它将满足双平方根算子方程的叠前波场转换成满足单平方根算子方程的波场.后者可以进行常规的动校正和水平叠加.事实上这种转换是消除动校正时倾角影响的一种倾角校正（DMO）方法.这是Stolt偏移法在DMO中的类似,它只需利用快速傅氏变换（FFT）以及附加的插值运算就可实现.文末附有算例.

| Abstract: | The wavefield transform DART is discussed, which transforms the prestack wavefield satisfying the double square-root equation to that satisfying the single square-root equation. The latter can be properly processed by conventional normal-moveout and common-midpoint stacking. The transform presented in this paper removes the dip-affection and is indeed a method of DMO. This transform, like the Stolt method in migration, can be easily performed by FFT and supplemented interpolation. |
