Abstract
Questions of using various techniques for processing echo signals in ultrasonic tomography instruments for extended complexly structured concrete articles are considered. Various algorithms are discussed for constructing tomograms of tested articles, techniques for radio engineering processing of ultrasonic signals, and different variants of nonlinear image transformations intended for increasing the signal-to-structural noise ratio and improving image quality.
