Paper Number: SEG-2010-0152
.... Introduction Vibroseis shot records can be obtained by two methods: the first one is by cross correlation of the sweep signal and vibroseis record; the second is by using the sweep signal to execute vibroseis deconvolution, in which the inverse filter is found using the sweep signal. Using a theoretical...

...). Because cross-correlation is sensitive to the slightest variation away from the ideal in the actual sweep, it is naturally error-prone, considering no vibrator can produce a seismic signal identical in every way to an electronic drive signal. An alternative method involves vibroseis deconvolution, which...
