ABSTRACT An accelerometer located on the pad of a vibratory seismic source provides a signal for comparison with the sweep signal which controls the vibrator. The error function representing the difference between the phases of these two signal is used to adjust the phase of the vibrator so as to maintain the vibrator in synchronism with the sweep signal. Prior to comparison with the sweep signal, the accelerometer output is conditioned by a tracking bandpass filter having its center frequency slaved to the instantaneous sweep frequency. Those components of the accelerometer output signal having a frequency equal to the instantaneous sweep frequency are passed by the bandpass filter and are subjected to approximately zero degree phase shift through the filter.
