Abstract

We propose a simple but effective technique for wraparound elimination that we call antiperiodic extension, based on a simple modification of the wavefield. We give a brief description of the Fourier differentiation and wraparound phenomenon. We then compare two methods for elimination of wraparound. The first is based on Cerjan's method, and the second on the concept of Fourier differentiation for an antiperiodically extended wavefield as developed in this note. For simplicity, we confine our attention to 2-D geometry, but the extension to 3-D geometry is straightforward. We employ a 2-D rectangular coordinate system with the z-axis taken positive downward.
