A Study to Evaluate the Efficiency of Beamforming the Lasa Long-Period Array

Abstract

The long-period vertical-component data from 18 teleseismic earthquakes recorded at the Montana LASA were prefiltered and time-shifted to determine the amount of signal loss, rms noise reduction, and signal-to-noise ratio improvement which results from beamforming.
