Optimization of hydroacoustic information systems of underwater vehicles to improve the efficiency of underwater search

The efficiency of activities related to the conduct of underwater search by robotic complexes is based on the optimization of hydroacoustic systems and search algorithms implemented. In turn, such algorithms, representing a set of certain actions, are directly dependent on the technical equipment of the underwater robotics. The article describes the peculiarities of the search activities and the corresponding algorithms, depending on the technical equipment of underwater vehicles. The analysis of the use of vision systems during underwater search, as well as the analysis of the effectiveness of search activities by hydroacoustic systems of underwater vehicles is carried out. The problems of their optimization on the basis of formation of narrow directional characteristic were considered, the ways of its realization were stated. The consequences of the influence of backscattering interference on the effectiveness of underwater vision systems are studied. A method for determining three spatial coordinates of an object of observation which can be used for precise orientation of underwater television means for identifying an object of observation is offered. Relevance of the issues of optimization of hydroacoustic information systems considered in the article does not cause doubts, as their introduction will provide increased efficiency of underwater search in comparison with the existing samples of underwater robotics.
