%X Based on the common-offset prestack time migration in f-k domain given by Dubrulle, we deduce a pair of common-offset plane-wave prestack time migration operator and its reverse operator. The common-offset plane-wave prestack time migration is carried out with a variable migration aperture in order to give a better imaging result. Further, the pair of the cross-conjugate operators is cascated to implement the seismic data regularization process. It is mentioned that the least-square seismic data regularization approach will greatly improve the numerical results. Numerical examples of the v(z) model and Marmousi model demonstrate that the approach is correct and effective.
