Abstract

Abstract

In this paper, we analyzed the waveforms of the two explosions that occurred on Dec.11, 2007 and Oct.9, 2006 as recorded using the HIA seismic station and the PS12 borehole seismic array. The results show that a borehole station can raise the signal-to-noise ratio (SNR) of the P waves to 4.6 times that of the common station at the same distance. With the beamforming technique, the SNR of the beamforming waveform from the PS12 is 3 times that from the single borehole station and over 10 times than that of the waveform recorded by the HIA. So the PS12 borehole seismic array can effectively improve the SNR of weak signals.
