Аннотация

A method is considered and an algorithm is developed that makes it possible to identify the layered structure of the propagation medium of a probing signal based on strip survey data from an interferometric side-scan sonar (ISSS) with antennas located in a vertical plane. Using the example of mathematical modeling of phase-difference measurements of ISSS for multilayer scattering planes, the capabilities of the proposed algorithm to determine their spatial position are demonstrated in the wave propagation medium. An analysis of the accuracy of calculating the position of scattering layers at heights (depths) and with different slopes was performed. The effectiveness of the method and algorithm for diagnosing the structure of layered media has been confirmed. The effectiveness of the method was tested on experimental data obtained using ISSS.
