Ushynskyy popup.description2 Research methods and equipment: A systematic approach was used that includes the development of a set of separate devices, blocks and programs that solve a number of separate tasks, combined with the overall goal: reliable identification, location and maintenance of the goal. The synchronization of sensors belonging to the acoustic intelligence-signaling system (AISS) and operating in a single communication channel is carried out by measuring the time of the communication session with the sensor and its inclusion in the formation of the event window. The multilayer perceptone is used to create structures of a neutron grid, which helps to recognize acoustic images. By means of nonlinear programming, the objective function of the error in the objective location problem is minimized by solving the corresponding system of nonlinear equations; the speed of execution of the algorithm is ensured by the implementation of the modified division method in half. The Kalman recurrent filter is used to solve the target maintenance problem. The LabView software environment is used to implement the specified software blocks and combine them into the general AISS functionality software. Infrasound sensors, which are based on the results of the first stage of research work, are used to register test acoustic signals in the development and testing of algorithms and software created at the reporting stage. Theoretical and practical results, novelty: A system and software that allows to receive real-time airborne signals from a single channel of communication with all sensors is developed. It is shown that a neural network with one hidden layer is capable of recognizing acoustic images by their amplitude-time characteristics. A modified dividing segment is implemented in half, which solves the spatial task of minimizing the target function by reducing the spatial cube by 16 times. Created a program to determine the coordinates of the source of acoustic waves. The effect of weight factors of the Kalman filter on the reliability of the definition of the trajectory of the target is investigated. Implementation efficiency: The results are used by the staff of the Main Center for Special Control during the conduct of research and experimental work in the field of geophysical monitoring. Area of use: Development and optimization of schemes of construction of optical and optical electronic devices and their systems, in particular acoustic intelligence-signaling systems.
