Signal processing techniques for the ultrasound characterization of complex materials
Résumé
This article focuses on the application of different signal processing techniques to improve the visibility of the echoes during travel time between the echo of entry (opposite echo), and the back wall echo (back surface) of longitudinal and transverse waves, it is easy to calculate the speed and longitudinal cross respectively, and then determine the elastic constants (Young modulus, Poisson’s ratio,) that allow us to describe the development of properties and split spectrum processing method.
