Abstract: Mathematical simulation is used to estimate the error in ultrasonic-echo measurements of the thickness of objects made of inhomogeneous materials with structural noise and frequency-dependent attenuation of ultrasound taken into account. Empirical formulas are derived for estimating the minimum measurement error. [ABSTRACT FROM AUTHOR]
