Abstract

For the fast calculation of the short time Fourier transform,the AFDISAR signal can be preprocessed by the proposed method to get a range of the speed of the slapper,and a range of the wavelet transform scale factor can be estimated.Then,the signal is analyzed by continuous wavelet transform method.The processing results of simulated interference signals suggest that the relative error is less than 2%.The displacement interferometer in high-speed detonation test is analyzed separately by method of short time Fourier transform,of wavelet transform and the method of short time Fourier transform combining with wavelet transform.The third method can recover the velocity history accurately,and calculate error is in the tolerated rang of the system.Taking calculating speed and calculating accuracy into consideration,the third method is chosen to the AFDISAR signal analysis.
