Исследование регистрируемого эхо-сигнала ультразвукового неразрушающего контроля с помощью Фурье и вейвлет преобразований и фрактального анализа

Abstract

In some studies, processing methods for studying ultrasonic wave signal use different methods of transformation and analysis, such as Fourier transform, wavelet transform, fractal analysis [1-4]. The relevance of this study is to find additional parameters that can characterize the registered ultrasound signal to get more information, as well as to optimize the algorithm for processing the ultrasound signal. The purpose of this work is to study the A-scan of the registered ultrasound signal using Fourier and wavelet transforms and fractal analysis in the MATLAB software package
