The application of Wavelet Transform in the processing of low frequency distortion of pyrotechnic shock signal

Spacecrafts such as missiles, rockets, spaceships, bear severe shock including high frequency energy when launching. This severe shock leads to voltage saturation of the preamplifier. As the result of this phenomenon, the low energy of the calculated shock response spectrum can't match the requ...

Summary:Spacecrafts such as missiles, rockets, spaceships, bear severe shock including high frequency energy when launching. This severe shock leads to voltage saturation of the preamplifier. As the result of this phenomenon, the low energy of the calculated shock response spectrum can't match the requirements of reliability and environment data processing. The approach based on Wavelet Transform presented by this paper recover real measured data, and settle the problem of low frequency distortion of shock response spectrum Now this approach has been used in the processing of measured data of some missile shock test successfully.
