To achieve this goal, the following research objectives were formulated, which defined the logic of the study and its structure: - research of existing methods and technologies of modeling and processing of hydroacoustic data; - study of aspects of modeling of hydroacoustic processes and creation of the concept of modeling complex; - development of modeling complex architecture; - development of algorithms of models of signal generation of hydroacoustic objects; - development of information models of the water area, the GAS and the marine object; - development of models archive maintenance; - development of controls for the hydroacoustic experiment and its implementation scenes; - development of tools for managing scenarios of experiments; - development of algorithms for processing hydroacoustic data of experiments; - development of a prototype of a software system for modeling hydroacoustic processes. The object of the study is the methods of computer simulation of hydroacoustic processes. The subject of the research are the tools for building a modeling complex for the study of hydroacoustic data. Research Methods: The following methods were used in solving problems of work: - analysis of hydroacoustic signals by Fourier transform; - determination of the direction to the radiation source by vector-phase transformations; - filtering of accompanying noise by means of the analysis of mutual spectra. Scientific novelty of the obtained results. The most significant scientific results of the study are: - development of the concept of construction of expert-modeling complex on the b Product Description popup.authors popup.nrat_date 2020-04-02 Close
