摘要： A technique includes receiving seismic data acquired in a seismic survey. The survey has an associated undersampled direction, and the seismic data contains samples, which are indicative of a pressure wavefield and a directional derivative of the pressure wavefield that contains information related to vertical variations. The technique includes relating the samples to the pressure wavefield or to the directional derivative of the pressure wavefield using at least one linear filter and based on the relationship, constructing a substantially unaliased continuous representation of the pressure wavefield or the directional derivative of the pressure wavefield along the undersampled direction.

摘要： A technique to reconstruct a seismic wavefield includes receiving datasets, where each dataset is indicative of samples of one of a plurality of measurements of a seismic wavefield that are associated with a seismic survey. The technique includes modeling the plurality of measurements of a seismic wavefield as being generated by the application of at least one linear filter to the seismic wavefield. The technique includes processing the datasets based on the linear filter(s) and a generalized matching pursuit technique to generate data indicative of a spatially continuous representation of the seismic wavefield.

摘要： A technique includes receiving data, which are indicative of measurements acquired by seismic sensors of a seismic wavefield. The seismic wavefield is formed from a combination of an upgoing wavefield and a downgoing wavefield. The technique includes providing a statistical estimator, which relates the upgoing wavefield to a linear combination of the measurements and a reconstruction error. The technique includes determining the upgoing wavefield based on the statistical estimator. The determination includes substantially minimizing a variance of the reconstruction error.
