摘要
介绍了小波变换的基本概念和特性.通过对岩石超声波检测信号的小波分析和处理,表明该方法在奇异信号检测和局部化分析方面具有优异特性.
The principles and features of wavelet transformation are introduced. Through the wavelet analysis and processing of the rock ultrasonic detection signals, it is indicated that wavelet transformation is advantageous to singular signal detection and partial analysis.
