Search for defects and assessment of the current condition of engineering structures with the help of georadars (review. Part II)

Abstract

The relevance. The development of technical means for non-destructive testing and remote sensing is an important practical task. This is primarily due to the fact that modern means of non-destructive testing open up ample opportunities for the introduction of new technologies and increase the economic efficiency of measures for the maintenance of various technical and construction objects at a relatively low cost of such work. In this regard, the development of computational algorithms for processing primary data and software products for the subsequent interpretation of the results obtained using computer engineering systems is of great importance. The purpose of the work is to review technical means, signal processing methods and some computer-oriented engineering systems for solving problems of detecting various defects in engineering structures and building structures. Materials and methods. The paper provides a brief overview of methods for processing primary data sets obtained using pulsed GPR. At the next stage, processing is carried out using the GeoVizy program. Finally, the main focus of the work is on the analysis of the capabilities of modern computer engineering tools. Also used the numerical - analytical methods of the modern theory of diffraction and methods of signal analysis in the space-time domain. Results. The results are based not only on scientific articles, but also on the analysis of the capabilities of modern computer modeling systems, as well as some mathematical models obtained by the author. Conclusions. The results presented in the article allow one to talk about a new direction in scientific research. This direction can be defined as combined multi-parametric analysis - CoMPA. The purpose of this direction is to conduct research of various interrelated processes in technical structures by using the methods of mathematical physics, combining not only the analysis of their interaction with fields of different physical nature, but also involving the appropriate models from various areas of mathematical physics. The significance of the results obtained consists not only of new models of data processing and interpretation, but also of the prospects for further progress in the field of technical means of control and diagnostics.
