The match or shaping filter can be used to minimize the differences between correlated vibroseis records on one hand and impulsive source records on the other. Figure 15 shows a match-filtering example. Here, trace 2 is a correlated vibroseis trace containing a nonminimum-phase symmetric Klauder wavelet. On the other hand, trace 1 contains a minimum-phase wavelet. The objective is to match trace 2 to trace 1. Although it is not perfect, the result is quite satisfactory.
