Prediction of Blast Shock Waveforms with Time Series Analysis Method

摘要

In the paper the blast shock waveforms are predicted by a time series analysis method that extracts the determinate terms from the original signals and then models the residual. Validity of the method is investigated by using two groups of waveforms recorded in the field. Results show that the method can obtain a high precision and therefore can be used to predict waveforms at different distances from the shotpoint within the range of field measurements.
