SUPPORT FOR DECISION-MAKING ON THE RATIONAL PLACEMENT OF ANTENNAS OF UNDERWATER COMMUNICATION SYSTEMS IN THE INTERESTS OF DISPATCHING OF GEO-SPACE PROCESSES

Abstract

The paper considers the main features of evaluating the efficiency of positional and mobile underwater communication systems with immersed correspondent objects at the stage of their design and deciding on the coordinates of the installation site of the transmitter-receiver antennas based on modeling and visualization of the expected underwater communication zones using intelligent geographic information systems. The influence of the quality of information support of geographic information systems on the accuracy of the calculation results of the expected zones of underwater communication in various hydrological and acoustic conditions is assessed. Research subject. The article is devoted to the issues of evaluating the efficiency of underwater communication and intellectual decision-making support for rational spatial distribution of receiving and transmitting antennas of underwater communication systems with immersed correspondent objects. Method. A method for optimizing (choosing a rational option) the spatial distribution of receiving and transmitting antennas of positional underwater communications or the depth of setting of lowered and towed antennas of marine underwater communications using specialized software and information tools and geographic information systems is considered. Core results. A new performance indicator is proposed in the form of the spatial volume of the underwater communication zone and a method has been developed to optimize the spatial distribution of the receiving and transmitting antennas according to the criterion of the maximum volume of the expected underwater communication zone for given hydrological and acoustic conditions in the area. Practical relevance. The introduction of the developed method into the systems of sonar calculations and automated decision support for advanced underwater communication systems will significantly reduce the decision-making time for the placement of antennas (when designing or planning applications) and increase the efficiency (stability and range) of underwater communication means with immersed objects - correspondents.
