Abstract

A perfect shock wave measurement and test system was established, the experiment of shock wave test was finished and the results were analyzed by using wavelet. In order to separate the effect of clutter interference from the test of shock wave, different signal processing methods were compared, and wavelet transform based signal processing method was proposed. This method is feasible and practical. The results show that the system is reasonable and reliable. The wavelet processing accurately judges signal discontinuities, separates signal noise and achieves energy of different bands.

Key words： shock wave; test system; wavelet transform; time-frequency analysis
