To standardize the processing flow of shock wave measurement data in damage experiment, an automatic batch processing method for shock wave measurement data were proposed based on the regional correlation principle of shock wave propagation. The adaptive filter was used in noise processing. The validity test of measurement data was realized by confirming the existence of step waveform in the time range of shock wave arriving at sensor. Mean value method was used to extract shock wave overpressure. Shock wave measurement data processing is efficient and automatic batch processing. The accuracy of data processing is improved.
