Abstract
The article concretizes the existing methodological approaches to the practical application of oceanological data in areas characterized by high environmental variability during the search by sonars. Quantitative characteristics of the operational oceanology output parameters are formed, based on the analysis of publications devoted to their description. These parameters are taken as initial data for solving optimization tasks. The general statement of the optimal control of sonars in the conditions of spatial and temporal environment variability problem is formulated. The solution of the optimal control problem using the zoning method and the mathematical apparatus of the search theory is given. The role and place of hydroacoustic calculation systems in solving the optimization problem is shown. The volume of the observation zone is proposed for use as a universal parameter characterizing the influence of the environment on the sonar efficiency. An example is given illustrating methodological approaches to optimizing the sonars in solving the search problem by a mobile observer in an ocean area with high spatial and temporal variability. Conclusions are drawn about the possibility of extending the methodological approaches given in the article to optimize sonars located on several mobile observers, as well as to solve the problem of optimizing the secrecy of the observer’s actions in the conditions of spatial and temporal variability of the environment. In conclusion, recommendations for the construction of software and hardware-software tools that provide the solution of applied problems using operational oceanology data are given.
