Description
Introduction The precise determination of the arrival time of transient signals like AE, seismograms or ultrasound signals is one of the fundamental problems in non-destructive testing and geophysics. The information of this time is important in event location, event identification and source mechanism analysis. Manual picks are time-consuming and sometimes subjective, especially in the case of large volumes of digital data. Various techniques have been presented in the literature and are routinely used in practice, such as a passing the threshold level, analysis of the LTA/STA (long term average/short term average), high order statistics or artificial neural networks.
