Abstract:
1. A seismic source, comprising: a reaction mass movable with respect to a geological structure; and an actuator moving the reaction mass, the movement of the reaction mass emitting a source signal as seismic energy into the geological structure, wherein the source signal is generated from a vibratory signal provided to the seismic source at a location, the vibratory signal including a plurality of segments of a base vibratory signal arranged together to generate the source signal, the base vibratory signal sweeping from an initial frequency to a final frequency, at least one of the plurality of segments having a partition of sweep frequencies different from at least one of the other segments, and wherein the vibratory signal has a distinguishing arrangement of the segments different from at least one other vibratory signal provided to another seismic source used in a seismic survey.
