Study of the Adaptive Beamforming Detector Using the Korean Seismic Research Station Short-Period Array

Abstract

A maximum likelihood constrained time-domain adaptive beamformer was evaluated for its detection performance using short-period data from the Korean Seismic Research Station (KSRS). A total of 132 events in Eurasia was used for the detection study, and two hour-long noise samples were used for false alarm investigation. The results indicated that the present adaptive beamformer yielded practically no increased detection capability from the aligned-sum beamformer at the KSRS Short-Period Array, suggesting that the present adaptive beamforming algorithm needs to be improved.
