A method for generating, recording and pre-processing high fidelity vibratory seismic data in a system that uses a plurality of vibratory sources (18, 20, 22 and 24) includes the steps of measuring the motion of each of the vibrators (18, 20, 22 and 24), determining a ratio by dividing the vibratory seismic data by the measured motion of the vibrator to remove the unknown applied force leaving the earth reflectivity times a time derivative divided by a minimum phase function, minimum phase band pass filtering (54) the resulting ratio and performing minimum phase deconvolution (56) to remove the time derivative divided by the transfer function of minimum phase. The method may also include the steps of shot ensemble deconvolution (66), receiver ensemble deconvolution (72), statics correction (88), F-K filtering (70) for noise, zero phase spiking deconvolution (74) and model dephasing (76). The vibrator motion is measured to provide a signal that is used to process the data. The data is divided by the relative of the actual transmitted signal in frequency domain.
