Seismic Array Processing Techniques. Extraction of Spectral Lines from Seismic Data

Abstract

Two methods for the removal in real time of stable spectral lines from seismic data were investigated. The first method involved the generation of a cosine wave, by means of a digital feedback system, to approximate the spectral lines. In this method, the cosine generator is adjusted in accordance with a mean-square-error criterion. This system of adjustment was simulated and proved to be unstable. In the second method, a Widrow adaptive prediction filter is used to remove the deterministic component. A simulation of this prediction method was carried out using one seismic data channel from a short-period array.
