FIG. 3.24 (A) A shot record with strong guided wave amplitudes along with its f-k spectrum (lower panel), and (B) same
shot after f-k filter to make the guided waves clearer.

FIG. 3.25 Analysis and suppression of guided waves by τ-p transform. (A) A band-pass filtered shot gather with guided
waves, (B) τ-p transform of the shot gather, (C) muting out of guide wave amplitudes, and (D) same shot gather after inverse τ-
p transform.
