System identification methods are applied to develop a parametric model of an ultra-sonic inspection situation consisting of a normal probe and a specimen. To simulate the probe behaviour at varying physical properties, a theoretical model is calculated to generate synthetic data. The comparison of the properties of the parametric model with that of the real or simulated probe shows a good agreement.
