摘要
在当代社会雷电灾害日益严重,对于雷电声音的研究具有重要的意义。通过对雷电声音的特征分析,使用一种合理的识别方法检测雷电,首先对采集的信号进行预处理和特征提取,然后与标准的雷声信号进行匹配运算,最后识别出雷声信号。根据识别的信号对于预防雷电危害具有重要作用。
In the contemporary society,lightning disasters is increasingly severe.The research on lightning voice has important significance,through the analysis of the characteristics of thunder voice,using a kind of rational recognition method for detection of lightning,first we should do the pretreatment and feature extraction for the signal,and then matching the operation signal with the standard of thunder.Finally we identify the thunder signal.The signal recognition of thunder for preventing lightning damage plays an important role.
