The directivity of the radiation of the receiving-transmitting converters is also taken into account by the model. On the basis of spatio-temporal transformations, the model allows to obtain a formula for the reconstruction of the image of discontinuities. Algorithms for signal selection and image formation from discontinuities based on the correlation of the spatial-temporal scan data set have been developed. As a result, it was possible to create an image with a higher signal-to-noise ratio. Product Description popup.authors Gevtsi Igor Ye.
