Abstract
This paper deals with two-dimensional wave equation migration in seismic Signal processing according to a frequency domain model. The required ideal phase specifications are approximated by a 2-D all-pass digital filter with symmetric half-plane hyperbolic impulse response. Examples are included to compare this recursive filtering approach with existing processing techniques.Keywords
