Abstract:Based on the repeatability and low signal-noise ratio of active source events, we propose an auto detection method of active source events using template matching techniques. A continuous waveform (25 200 seconds) of CKT(SHZ) is processed by a program using template matching and correlation calculating techniques. 13 air-gun earthquake events are detected and the trigger times are picked up. The results indicate a 100% accuracy with no misdetections. The method can be used for auto data handling processes for active source or seismic arrays that produce huge amounts of waveform.
