The Tau-p Transform — Aliasing Considerations and Application to High Resolution Seismic Data

The tau-p transform is still a relatively new and novel seismic data processing technique. As with other transforms used in digital seismic data processing, problems are encountered in choosing the appropriate discretization to avoid aliasing. A diagrammatic method of understanding the aliasing concept in tau-p domain is presented. Examples of the correctly applied tau-p transform velocity filters are presented and show the excellent capabilities of the technique. Convenient methods for enhancing events on the basis of their coherency are also made available by the transform. An example of one of these methods is presented along with a more novel application of enhancing events with characteristic travel times as well as moveouts.
