Should vibroseis records be correlated? The signature of a vibroseis record is the sweep signal, which is recorded separately from the received seismic trace. The Klauder wavelet is the autocorrelation of this signature. In vibroseis processing, it is traditional (as the first step) to correlate the received trace with the signature (i.e., the sweep signal), which replaces each sweep signal on the trace by the Klauder wavelet. The Klauder wavelet is a broadband zero-phase signal, so it is an ideal interpreter wavelet.
