Abstract
A technique includes receiving sensor acquired data, which includes pressure data representative of at least one pressure measurement of a wavefield and particle motion data representative of at least one particle motion measurement of the wavefield. The technique includes filtering the pressure data and the particle motion data with a plurality of directional filters to provide a plurality of filtered datasets. The filtered datasets are associated with different directional ranges. The technique includes estimating an angle of incidence for at least one of the directional ranges based at least in part on at least one of the filtered datasets; and processing the acquired data to determine at least one of an upgoing component of the wavefield and a downgoing component of the wavefield based at least in part on the at least one estimated angle of incidence.
