To eliminate their impacts, it is necessary to carry out anti alias trace interpolation, especially for the reflected waves from VSP and cross hole seismic, because they are of steep slope, we use the anti alias trace interpolation in F-K domain.

• 为了消除其影响 ,需要进行道内插 ,特别是VSP和井间地震反射波具有陡斜率的特点 ,因此 ,道内插去假频显得尤为重要。 我们采用了F -K域抗假频道内插。
