A method and apparatus for generating a seismic source signal are provided for generating energy in the form of a plurality of time sequence vibratory signals, the vibratory signals being partitioned as a function of time and/or frequency, wherein each of the plurality of signals comprises a distinguishing signature. The partitioned vibratory signals are emitted into a terrain of interest as seismic source signals for conducting a seismic survey.

Acquiring seismic vibrator signals having distinguishing signatures

A seismic system has a plurality of seismic sources. Each of the seismic sources includes a reaction mass movable with respect to a geological structure and includes an actuator moving the reaction mass. The movement of the reaction mass emits a source signal as seismic energy into the geological structure. In the system, each of the source signals is generated from a base vibratory signal segmented into a plurality of segments, where the base vibratory signal sweeps from an initial frequency to a final frequency. Each of the segments has a partition of sweep frequencies different from the other segments. Each of the source signals has a distinguishing arrangement of the segments different from the other source signals.
