Claim:
1. A system to acquire blended seismic signals, comprising: a plurality of seismic sources of a survey region that activate based on a timing function that includes a ratio of a dither time to a shot interval that is less than or equal to ½, wherein the dither time indicates a delay between two shots from two different seismic sources of the plurality of seismic sources and the shot interval indicates a delay between two shots from an individual seismic source of the plurality of seismic sources; a plurality of seismic sensors deployed at a plurality of positions in the survey region to record seismic signals generated in response to activation of the plurality of seismic sources; and one or more processors to deblend, based on the timing function that includes the ratio of the dither time to the shot interval that is less than or equal to ½, the seismic signals recorded by the plurality of seismic sensors to generate data representing subsurface structures indicative of oil or gas.
