ABSTRACT:
A field quality control system and real-time method for evaluating the performance of swept frequency vibrators is provided. The system includes independent sensing means adapted to be mounted with the swept frequency vibrators for developing signals representative of reaction mass accelerations and baseplate accelerations, and means for monitoring the swept frequency vibrator's pilot signal. The system also includes a signal calculating means for determining vibrator operating characteristics from the pilot sweep signal, reaction mass acceleration signal, and baseplate acceleration signal and processing means for processing the vibrator operating characteristics to obtain analysis characteristics for evaluating and adjusting the performance of the swept frequency vibrator. In operation, the present invention provides a method for analysis characteristics to analyze and adjust the performance of swept frequency vibrators in real-time on location.
