Vibration Controller of Marine Electromagnetic Vibrator

Marine electromagnetic vibrator is a non-explosive seismic source, for high resolution detection of marine seismic exploration, which used sublevel sweep mode of marine electromagnetic vibrator. The vibration controller provides sublevel Chirp signal by marine geology condition. The Chirp signal was sent to exciter through power amplifier. Exciter coupled with marine water by shaking base plate, the elastic wave was sent to marine .The vibration controller is the source of marine vibrator, so the quality of signal influences the whole performance index of seismic explosive system. This thesis discusses hardware and software of marine electromagnetic vibrator controller.
