Abstract
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.
Claims27
A geophysical information acquisition method, comprising:
- receiving seismic energy from a plurality of source signals at one or more receivers positioned relative to a geological structure;
- and
- storing the seismic energy from the source signals for processing,
- wherein each of the source signals is generated from a base vibratory signal segmented into a plurality of segments, the base vibratory signal sweeping from an initial frequency to a final frequency, each of the segments having a partition of sweep frequencies different from the other segments, and
- wherein each of the source signals has a distinguishing arrangement of the segments different from the other source signals.

A geophysical information acquisition system, comprising:
- one or more receivers positioned relative to a geological structure and receiving seismic energy from a plurality of source signals;
- and
- a processing device operatively coupled to the one or more receivers and storing the seismic energy from the source signals in memory for processing,
- wherein each of the source signals is generated from a base vibratory signal segmented into a plurality of segments, the base vibratory signal sweeping from an initial frequency to a final frequency, each of the segments having a partition of sweep frequencies different from the other segments, and
- wherein each of the source signals has a distinguishing arrangement of the segments different from the other source signals.
