Abstract
Distortion in vibrator-type seismic records is corrected by measuring and using the actual ground force imparted by the source to develop an inverse filter. The ground force signal and the reflected seismic data are both subjected to the same deconvolution or other standard processing technique, thereby automatically filtering out flaws introduced by any such technique.
