TRACE INTERPOLATION IN SEISMIC DATA PROCESSING *

Trace interpolation of spatially aliased seismic data is used to improve the quality of multi-trace processing, especially that of migration. We consider non-rectangular sampling lattices. After stating the real sampling requirements for (two-dimensional or 3-D) digitized signals, the paper explains geometrically the effect of migration and of the 2-D dip filtering upon the aliased events, as well as our ability to interpolate traces from undersampled seismic data.
