Pann, K; Fields, J L

In seismic exploration of the earth's formations, a method is described of suppressing aliasing caused by coarse sampling along a line of exploration consisting of: gathering seismic traces representing the amplitude of seismic reflections as a function of time and distance along the line of exploration; inserting zero amplitude traces between the seismic traces; transforming the traces into an f-k array of digital samples representing amplitude as a function of frequency and wave number; filtering the f-k array with a filter which mutes all samples in a region of frequency and wave number which has aliasing; and transforming the filtered f-k array into a seismic section representing amplitude as a function of time and distance.
