Short Period Signal-to-Noise Ratio at NORSAR

Abstract

Analysis of nine events recorded by the NORSAR short-period array reveals that a beam of the ten Northeast subarrays has only .06 magnitude units less detection capability than the full array and that the 3C subarray has only .18 magnitude units less capability. The study shows that if the 3C subarray were expanded to 56 elements inside a 15 km diameter circle it would have .3 magnitude units more detection capability than the present full array.
