Analysis and treatment of measured pyrotechnic shock data

The wide-band and big acceleration pyrotechnic shock environment usually cause measured data distorted. Only when measured pyrotechnic shock data was analyzed, confirmed and corrected, can it be put into practice. The effects of slew rate of amplifier on signal frequency were analyzed, at the same time, the reason why zero-shift of measured pyrotechnic shock signal occurred was discussed. Distorted shock waves were decomposed and restructured by wavelet technique, and actual pyrotechnic shock signal was extracted.
