The Wavelet Analysis and Measurements of Strange Noise on the Light Rocket Launcher
Hongwei Ma · Journal of Projectiles.Rockets.Missiles and Guidance · 2004
The shock wave and strong pulse noise, which produced by light rocket launcher, are belong to a non stationary signal process with a wide frequencies. However, it's difficult to get the expected results by using Fourier analysis method to analyze these signals. In order to overcome the disadvantages of Fourier analysis in the signal process, the wavelet method is used to analyze these strong pulse noises in this paper. Some useful results are obtained finally.
