dc.description (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). A companion is the comprehensive book on Time-Frequency Signal Analysis and Processing available at: http://www.elsevier.com/locate/isbn/0080443354 en_US
dc.description.abstract The Wigner-Ville distribution (WVD) has been shown to concentrate signal energy along the instantaneous frequency law of an emitted Vibroseis source signal. Thus, the WVD is proposed as a basis for achieving event separation for a received Vibroseis signal in the time-frequency (t-f) plane. The WVD has previously been used to determine Earth absorption parameters from the first down going arrival of a Vibroseis signal from a vertical seismic profile (VSP). This method can be extended to the multicomponent signal case, but only if a successful t-f plane event separation can be achieved. This is obtained by using the cross Wigner-Ville distribution (XWVD). The authors also show that the XWVD can be used as the basis for absorption and dispersion determination from a received Vibroseis signal, and for a two dimensional processing of VSP data. en_US
