为了更好地分析和处理弹载固态记录仪所记载的助推火箭在发射时对弹体的冲击和振动信号 ,本文利用小波变换所具有的空间局部化性质 ,在对原始采样数据的奇异性及奇异性位置和奇异度的大小的分析中 ,以及在导弹型号试射实验的后视数据分析中 ,取得了良好的分析效果 In order to better analyze and process the impact and vibration signals of the projectile on the projectile when the projectile rocket is recorded by the onboard solid-state recorder, this paper makes use of the spatial localization of the wavelet transform and the singularity of the original sampled data And singularity and singularity of the size of the analysis, as well as the missile model test of the rear-view data analysis, and achieved good results
