Next: Temporal filtering Up: Antialiasing of Kirchhoff operators Previous: Introduction

Overview of existing methods

I start with reviewing the existing approaches to operator antialiasing and discussing their main principles and limitations. The two reviewed approaches are temporal filtering, as suggested by Gray (1992) and Lumley et al. (1994), and Hale's spatial filtering technique, developed originally for an integral implementation of the dip moveout operator (Hale, 1991).
