The method of statistical phase ultrasonic thickness measurement of products from materials with considerable attenuation of ultrasonic oscillations, based on analysis of phase characteristic of signals, was developed. The procedure and results of modeling the signal processing in Matlab environment are given. 10 Ref., 3 Fig.
