摘要：

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 filter1 with symmetric half-plane hyperbolic impulse response. Examples are ‘included to compare this recursive filtering approach with existing processing techniques. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
