Blind Deconvolution of Ultrasonic Signals Using High-Order Spectral Analysis and Wavelets
Roberto H. Herrera, Eduardo Moreno, Héctor Calas +1
Defect detection by ultrasonic method is limited by the pulse width. Resolution can be improved through a deconvolution process with a priori information of the pulse or by its est…

Wavelet-based deconvolution of ultrasonic signals in nondestructive evaluation
Roberto Henry Herrera, Rubén Orozco, Manuel Rodríguez
In this paper, the inverse problem of reconstructing reflectivity function of a medium is examined within a blind deconvolution framework. The ultrasound pulse is estimated using h…
