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.

Abstract: Performing seismic data processing using frequency diverse basis functions and converting a data processing problem into a one-norm or zero-norm optimization problem, which can be solved in frequency-space domain. The data processing problems can be data deghosting, data regularization or interpolation. The data being processed can be aliased or un-aliased, single sensor data or group-formed data, single component or multi-component data single source data or simultaneous sources, or some combinations.
