Abstract

Formulas are derived that relate the strength of the crosstalk term in multisource imaging to the variance of random changes in static time, amplitude, and polarity changes in phaseencoded supergathers. Analysis reveals that the crosstalk term is exponentially reduced with increasing variance of the static shift and increasing source frequency. Formula also suggest, under ideal circumstances, that the number of iterations should linearly increase with the number of shot gathers/supergather to achieve acceptable accuracy in the final image. These conclusions should be valid for least squares migration or waveform inversion of phase-encoded multisource supergathers.
