Currently, ultrasonic monitoring technology is widely used using ultrasonic antenna arrays that emit and receive waves in the object under study. Two technologies for image reconstruction of reflectors using antenna arrays have found wide application in the practice of ultrasonic testing: phased array antennas (FAR) and digital focusing of the antenna array (CFA). In this paper, both technologies are compared, and it is concluded that the CFA technology is more promising in terms of using a variety of image reconstruction algorithms for reflectors.
The overview report analyzes the current achievements and prospects in the field of advanced ultrasonic inspection technologies: automation, robotization, access to the cloud, protection of documents from forgery, self-diagnosis of equipment..

Igor Nikolaevich has educated about thirty candidates and doctors of sciences. His students scattered all over the former USSR, and there are them in Europe. And his theory of the acoustic path has made its way without exaggeration all over the world. This book is a tribute of love and respect to a great scientist and a wonderful person.
The collection includes the most interesting works performed by the ECHOPLUS team in recent years. Simultaneously with the development and use of automated ultrasound systems with coherent data processing, the following are presented works devoted to the research, development and application of devices with phased array antennas. New electronics, scanning systems, and image quality improvement algorithms are described. The basic principles of building control techniques using such systems are considered. The question of the ratio of radiography and ultrasound in non-destructive testing is investigated. It has been shown that coherent automated ultrasonic inspection in some cases gives results no worse, and in combination better, than radiography. The experience of using a computer programming program is given modeling the tasks of the "CIVA" ultrasound inspection center for the development of ultrasound control techniques.

The collection of articles includes the main works of the ECHOPLUS Company team dedicated to the creation of automated ultrasonic control systems for hazardous industrial facilities. It is noted that the use of coherent data processing methods in automated ultrasonic systems made it possible to make the transition from flaw detection to flaw detection with access to an assessment of the residual resource. The new technology has found wide application in leading sectors of the national economy, primarily in nuclear energy, Gazprom, Transneft, and Russian Railways. The results of the development of Augur series systems and their application in these areas are presented. It is shown that the use of automated systems gives a significant technical and economic effect.

The issues of theory and practice of ultrasonic flaw detection based on the application of digital acoustic holography algorithms in relation to the operation of high-risk facilities are considered. The features of various algorithms for obtaining a coherent image are given, including: projections in spectral space, angular spectra, reference holograms, etc. The developed Augur series equipment and its modifications in relation to various control objects are described in sufficient detail. It is shown that the information about the type and size of defects obtained during holographic control is sufficient to assess the residual resource of the object. Based on the results of numerous metallographic studies, the error in measuring the size of defects, which is 1.5 mm, has been estimated. More than 10 years of experience in the application of Augur series systems, primarily at nuclear power facilities, is given; signs of defect types and algorithms for automatic determination of their parameters are formulated. The methodological foundations of holographic control of a wide range of welded joints have been developed, which made it possible to create and certify 13 specialized techniques. Of interest are systems for the diagnosis of railway carriage wheelsets using digital acoustic holography, in which a specially developed program for determining the residual life is used. Promising methods for improving the resolution and quality of defect images are described.

The handbook is intended for specialists in narrow-field engineering with qualifications of at least the second level, developing inspection methods and converters. The main focus is on physical control issues. Of the methods, the echometode is considered in detail, since it finds the greatest application.The values are expressed in SI. In space-time problems, more convenient derived units are used: for time – mks, for frequency – MHz, for distances – mm.
