Abstract

Lattice digital filtering techniques have only recently been exposed to any significant extent through the technical literature, primarily in articles not directly related to reflection seismology. The most basic 'all-zero' lattice filter dates back only around a decade.This paper first reviews current technology in adaptive lattice filtering from the standpoint of seismic deconvolution. An 'all-pole' deconvolution technique is developed next; then a new 'pole-zero' lattice is adapted to seismic deconvolution, and operational methodologies for its effective implementation and stabilization are developed. Some advantages of deconvolution by lattice filtering and other potential applications of lattice filters to seismic data processing are suggested.The adaptive abilities and effectiveness of seismic deconvolution by the three lattice types are tested and compared with stationary Wiener deconvolution. The test data are realistically nonstationary, thus allowing all three of the adaptive lattice filters to perform favorably in comparison to the nonadaptive or stationary Wiener filter.
