Description

A recently-developed model allows the prediction of echo-responses from targets of various geometry and acoustic impedance [1,2]. The model is briefly reviewed then used to predict echo-responses from angled planar targets, these results being compared with experimental measurements. This comparison allows the definition of its domain of applicability. Implications for QNDE are discussed. Particular attention is given to the physical interpretation of the results in term of scattering of the geometrical and edge wave components of the incident field.
