| Abstract: | Wavelet transform was used for analyzing features of the flaw signals in ultrasonic testing of concrete. Features based on power spectrum and wave shape of the decomposed signals were extracted. Finally, a fuzzy feedforward neural network classifier was used for the features. Experimental results show that the method is effective. |
