Antialiasing of Kirchhoff operators by reciprocal parameterization

Sergey Fomel

Abstract:

I propose a method for antialiasing Kirchhoff operators, which switches between interpolation in time and interpolation in space depending on the operator dips. The method is a generalization of Hale's technique for dip moveout antialiasing. It is applicable to a wide variety of integral operators and compares favorably with the popular temporal filtering technique. Simple synthetic examples demonstrate the performance and applicability of the proposed method.
