Abstract
Methods, apparatuses, and systems are disclosed for processing seismic data. In some embodiments, a set of vectorial measurements and a set of corresponding scalar measurements of a seismic wavefield may be obtained at a seismic receiver. An angle of incidence of the seismic wavefield at a first instance of time may be determined by calculating an incidence vector of the seismic wavefield at the seismic receiver at the first instance of time, with the incidence vector derived from a measure of correlation of at least one of the vectorial measurements. A component of a vectorial measurement may be corrected with the determined angle of incidence of the seismic wavefield at the first instance of time, and the corrected component may be combined with a scalar measurement that corresponds to the first instance of time.
