Abstract
A system and method controls impulsive source activations in a blended acquisition marine seismic survey. A component of the system generates a sequence of dither values deterministically and stores the sequence of dither values, or source activation indicators derived therefrom, in a non-transitory medium readable by a control system operable to execute shot points during the survey responsive to the values stored in the medium. According to some embodiments, generating the dither values comprises iteratively selecting from a fixed set of candidate dither values to produce a candidate sequence of dither values. The selecting is based on evaluating one or more quantitative measures of randomness and one or more quantitative measures of separation exhibited by at least a portion of the candidate sequence of dither values. Generated sequences improve deblending results by reducing coherence exhibited by the dither values in the sequences.
