Focal transformation, an imaging concept for signal restoration and noise removal
AJ Berkhout, DJ Verschuur - Geophysics, 2006 - library.seg.org
Interpolation of data beyond aliasing limits and removal of noise that occurs within the
seismic bandwidth are still important problems in seismic processing. The focal transform is …
