Generalized Linear Filtering of Seismic Array Data

Abstract

The theory of generalized linear filtering (Oppenheim, 1966, 1969) is applied to the problem of averaging the transfer functions between a seismic source and seismic recording stations on a continental-sized array. To provide synthetic data for a test of the processor, a simple source signal is passed through nine different random perturbations of a velocity-depth structure yielding nine different synthetic seismograms. Two nuclear explosions (LONGSHOT and MILROW) and an Andreanoff Islands event (22 November 1965) are also processed. The earthquake appears to have longer time terms remaining after generalized linear filtering and the nuclear events appear more similar (before the arrival of the depth phase).
