Description
Summary:The theoretical work presents elaboration of continuous wavelet transform parameters for problems of ultrasonic thickness gauging. The advantage of the processing method using synthesized wavelets as compared with the correlation method in case of difference between an extracted signal and a reference one at signal-to-noise ratio of 1-3 has been shown using the stability criterion.
