摘　　要：便携式火箭发射器所产生的冲击波和强脉冲噪声属非稳态信号,具有较宽的频率范围。用Fourier变换来分析非稳态信号的频率特性,在实际分析中难以达到所期望的效果。为了克服Fourier变换在时—频局部化方面的不足,文中采用小波分析方法对强脉冲噪声进行了分析,得到了一些有用的结论。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.
