Abstract
Beamed data can be obtained from shot gather data, and debeamed data can be obtained from beamed data. Shot gather data for a geophysical volume of interest in a first domain and/or beamed data in a third domain may be received. The first domain has a component relating to seismic wave propagation time and a spatial component relating to lateral spacing. The third domain has a component relating to local plane wave arrival time at a beam center surface location and a component relating to plane wave arrival directions. Data may be transformed between the first domain and a second domain. The second domain has a frequency component and a spatial component corresponding to the spatial component of the first domain. A forward or reverse transform may be applied to transform shot gather data in the first domain to/from beamed data in the third domain.
