Abstract

It is shown that the imaging algorithm, that is widely used in ultrasonic tomography of concrete building structures and based on the sequential focusing of the probing signal to each point of an object under monitoring and subsequent formation of tomographic image of the product, is focused on the visualization of point reflectors, while it relatively poor displays planar ones. At that, the tomographic image formation accuracy depends on adequate choice of value of ultrasound velocity in concrete. In addition, it is shown that basing on the application of “focusing to point” algorithm it is possible to implement standard-exclusion method for simultaneous determination of ultrasound velocity and failure location in non-extended products made of homogeneous materials.
