Klauder wavelet

From SEG Wiki

(klau’ d∂r) The autocorrelation of a vibroseis sweep. The vibroseis (q.v.) process of injecting a sweep of frequencies into the ground and then correlating with the sweep pattern to yield a seismic record is equivalent to convolving the reflectivity with the autocorrelation of the vibroseis sweep, so that the Klauder wavelet is in effect the seismic source waveform for correlated vibroseis records. It is not restricted to linear sweeps because a nonlinear sweep can be thought of as the superposition of linear sweeps. Named for John Rider Klauder (1932–), American mathematician.
