Abstract

The type of output used to control a vibrator was a subject of controversy some 25 to 30 years<br>ago. The field data collected by the acquisition systems must be correlated by a “pilot” signal<br>for the results to be comparable with impulsive data. But which vibrator signal corresponds to<br>the going down signal? A great discussion started. Baseplate velocity had been used as the<br>feedback control, as well as reaction mass acceleration. Over the years, the use of ground<br>force, measured as the weighted sum of baseplate and reaction mass accelerations, has found<br>wide acceptance.
