Abstract

System and method for shooting plural seismic sources Si in a marine acquisition system with a deblending-designed dithering sequence DSnew. The method includes generating the deblending-designed dithering sequence DSnew to include random dithering times Di, a range of the dithering times Di being larger than a preset, non-zero, minimum value pmv; selecting a shooting sequence SS for the plural seismic sources Si; and shooting the plural seismic sources Si with the deblending-designed dithering sequence DSnew, based on the shooting sequence SS. All odd or all even members of the shooting sequence SS are shot with zero dithering times.
