摘　　要：小波分析克服了短时傅里叶变换固定分辨率的弱点,既可分析信号的概貌,又可分析信号的细节,利用小波变换来分析信号的奇异性及奇异性位置和奇异度的大小是非常有效的,该文提出了火箭弹道测量数据奇异性分析的应用方案,并分析了实际弹道测量数据的奇异性,得到了弹道测量数据奇异性检测的小波分析的新方法。Wavelet analysis have overcomed Fourier method in multiresolution analysis.Wavelet method can not only analyze the sum of the signal,but also can analyze the detail.Wavelet method is good for analyzing singularity in position and in degree.They have found out singularity of the ballistic trajectory measure data analyzing and processing new method on the base of wavelet theory. In that paper, they have used this method to analyze and interpret the data, party provide the processed and analyzed experiment dat...
