This study is devoted to the consideration of methods for creating mathematical models of acoustic coherent images in relation to the tasks of monitoring the underwater environment of the World Ocean using modern distributed information and telecommunication networks. The combination of the theoretical approach to constructing an acoustic image as a section of the secondary field at the aperture of the receiving antenna, and the experimental method for obtaining such images with instrumental measuring instruments of a hydroacoustic tank was chosen as the main research method. Comparison of theoretical and experimental results makes it possible to verify the proposed mathematical models of acoustic coherent images. The proposed models, confirmed experimentally, make it possible to perform computer simulation of the processes of formation and processing of acoustic coherent images (ACI) to solve the problems of creating and improving methods for processing such images for their recognition and classification, as well as for testing the technical means of underwater monitoring networks during their tests.
