摘要
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 。
In order to analyze and process the impact and vibration signals between boost rocket and missile which are recorded by sampler on board,this paper takes advantage of the spatial localization feature of wavelet in the analysis of the oddity of original signal and its precise position and value.What's more,this procedure also acquires adequate good results in the original data analysis of missile launch experiments.
