In order to realize the overloading dynamic characteristics of shell comprehensively and objectively in the process of penetration into target, the non-stationary penetration acceleration signals must be processed. In the paper, the actual acceleration signal which was obtained in the test of projectile penetration into target is analyzed, such as pretreatment, integral analysis in the time domain, by Fourier transform in the field of frequency. This paper has a wavelet analysis on the signal, gets the characteristics of the penetration acceleration signal based on signal processing and the comprehensive analysis and provides a kind of data processing method to get the concerned data for engineers.
