METHOD FOR STABILIZATION OF LOW FREQUENCIES IN TAU-P DOMAIN FILTERING AND DECONVOLUTION

摘要

Apparatuses andmeth-ods for collecting and analyzing seismicdata (D) include a frequency dependentnoise factor (.epsilon.2) for stabilizing atrans-formation matrix (S). The noise factor(.epsilon.2) is a function of a number of nonzeroeigenvalues of the transformation matrix(S).
