Abstract

A technique includes obtaining seismic data indicative of measurements acquired by seismic sensors of a composite seismic signal produced by the firings of multiple seismic sources (114). The technique includes associating models that describe geology associated with the composite seismic signal with linear operators (118) and characterizing the seismic data as a function of the models and the associated linear operators (122). The technique includes simultaneously determining the models based on the function (126) and based on the determined models, generating datasets. Each dataset is indicative of a component of the composite seismic signal and is attributable to a different one of the seismic sources (130).
