Method and system for seismic acquisition using a dispersed source array and spectrally non-overlapping sources

A system for seismic acquisition comprising:

• a dispersed-source array (DSA) comprising two or more sources, a control subsystem comprising circuitry configured to:
• a. for each of the two or more sources of the DSA, determine an individual spectrally-banded waveform;
• b. for each of the two or more sources, form a primary waveform by repeating the individual spectrally-banded waveform;
• c. for each of the two or more sources, form a secondary waveform based on the primary waveform, wherein each of the secondary waveforms is spectrally shifted relative to the primary waveform, such that the secondary waveforms of the two or more sources are spectrally non-overlapping;
• and
• d. provide the blending operator based on the secondary waveform of each of the two or more sources to the DSA;
• wherein the DSA is configured to:
• emit wavefields based on the provided blending operators;
• and
• acquire seismic data from the emitted wavefields;
• and
• wherein the circuitry of the control subsystem is further configured to:
• perform deblended-data reconstruction of the acquired seismic data based on one or more properties of the blending operators of the two or more sources;
• and
• store the deblended seismic data.
