Abstract :
An algorithm is proposed for remote definition of physical-mechanical and geometric parameters of thin spatial elastic inclusions with varying thickness. It is assumed that mechanical characteristics of inhomogeneity and matrix differ insignificantly in comparison with the inhomogeneity relative thickness. The elastic longitudinal waves are sounding waves and the unknown parameters are defined in terms of the scattering amplitudes of these waves in the Fraunhoffer zone
