Abstract :
Nowadays the use of pattern recognition for signal processing presents a novel approach in order to determine temporal distance based upon echoes analysis. The aim of this work is to detect the thickness of a composite material based upon pulse echoes using ultrasonic measurements. This approach is performed by the processing of an ultrasonic measurement using wavelets technique and ART2 Networks
