  • Seismic source vibrator having improved sweep generator
    Patent number: 4766576
    Abstract: A sweep generator for a seismic source vibrator provides for any one of a variety of sweep signals governed by input parameters. Selected analytic functions may be entered which are solved to provide a plurality of sweep parameters. The sweep parameters may also be directly entered by the operator. The time and frequency sweep parameters (or time and amplitude) are then employed to generate polynomial coefficients for consecutive use in a polynomial equation. The polynomial equation is repeatedly solved to generate a series of instantaneous frequencies or instantaneous amplitudes which are applied to an analog wave synthesizer. The analog wave synthesizer then generates an approximation to the desired sweep signal for input to the hydraulic system of the vibrator.
