Paper, starting from the point of view of the wavelet transform, introduced by a division of the signal energy scale domain, wavelet energy spectrum and wavelet entropy feature as a signal feature extraction amount to reflect the statistical characteristics of the system signals. The experimental results show that the algorithm can effectively extract the the projectile shock signal characteristics, speed, high accuracy, and is not sensitive to noise advantage.
