PRELIMINARY EVALUATION OF NORSAR

Abstract

A preliminary evaluation of NORSAR, using short-period data from one noise sample and two teleseismic events, was performed to determine: (1) the minimum inter-sensor spacing required to produce optimum rms noise reduction by summing, and (2) the amount of signal loss, rms noise reduction and signal-to- noise gain produced by beamforming the array.
