Abstract
A seismic data processing system utilizes vibration type shock waves which are delivered by a reactive mass (52) acting in conjunction with a base plate (50) to output low frequency shock waves to the earth. The force signals for the reactive mass (52) and (50) are measured and input to a transmitter (42) for transmission to a receiver (48) at a control center (28) which also receives resultant measured data. The measured force signal is input to a data correlator (74) as a model signal and correlated with the resultant data to provide processed data out.
