A technique is designed for conducting a seismic survey. The technique comprises: providing at least two vibrator arrays to conduct a seismic survey, each of the vibrator arrays comprising a low frequency vibrator and a high frequency vibrator; continuously sweeping low-frequency signals with the low-frequency vibrators in the at least two vibrator arrays; and employing the high-frequency vibrators to emit at least partially simultaneous sweeps that have a shot phase that is a function of a shot position. 0",-20 24, FIa. 1 32>, 01-24 30< |
