Abstract:
|
It has been shown that the XWVD offers a suitable time-frequency
replacement for the cross-correlation function used in processing
Vibroseis seismic data today. In terms of peak width, no extra
resolution is gained. The major gain rests with the fact that the
time-variant nature of the spectral content of the recorded signal can
easily be observed and compensated. This is not easily achieved with
the cross-correlation function and time variant deconvolution. Further
justification for the method is presented by Boles [5] where particular
attention is given to the pha..se characteristic of the XWVD. |

Description:
|
This paper shows that the XWVD offers a suitable time-frequency replacement for the cross-correlation function used in processing Vibroseis seismic data today, using the phase characteristic of the XWVD.
(Additional details can be found in the comprehensive book on Time-Frequency Signal Analysis and Processing (see http://www.elsevier.com/locate/isbn/0080443354).
In addition, the most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia, and then continuously updated). |
