Antileakage Fourier Transform based data regularization is inversion technique whereby one plane wave at a time from strongest to weakest is modeled and subtracted from input trace location (irregular) domain and added to the regular output trace location domain. 

We offer highly efficient 3D, 4D, and 5D data regularization in midpoint x, yand vector offset (offset X, offset or azimuth, absolute offset) dimensions.
