Estimate of the Potential Accuracy of Thickness Measurements of Objects Made of Materials with Complex Structures with Frequency Dependent Ultrasound Attenuation

Resumo

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.
