| 摘 要： | 由于爆炸分离冲击环境的频带宽(可到100 kHz)、加速度大(可到300 000gn),常常导致测量数据失真。对实测的爆炸分离冲击数据应分析、确认、修正后才能使用。分析了放大器的压摆率对信号频率的限制,讨论了某实测爆炸分离冲击信号零漂产生的原因,应用小波分析的方法对失真的冲击波形进行了分解和重构,提取了真实的爆炸分离冲击信号。

| Abstract: | The wide-band and big acceleration pyrotechnic s hock environment usually cause measured data distorted.Only when measured pyrot echnic shock data was analyzed,confirmed and corrected,can it be put into practi ce.The effects of slew rate of amplifier on signal frequency were analyzed,at t he same time,the reason why zero-shift of measured pyrotechnic shock signal occ urred was discussed.Distorted shock waves were decomposed and restructured by w avelet technique,and actual pyrotechnic shock signal was extracted. |

| Keywords: | pyrotechnic shock wavelet amplifier saturation |
