Abstract

The article carries out a literature review and investigates the existing methods of determining the coordinates of the location of the acoustic signal source. The advantages and disadvantages of passive and active methods given in the article are highlighted. These methods can be used in aviation, cosmonautics, mechanical engineering and other fields of science and technology, where measurements are used, and are designed to determine the coordinates of the acoustic signal source. Recently, there has been a growing interest in using neural networks to solve various problems and their application in various fields. With the help of artificial neural networks, it is possible to process, analyze and summarize information. The authors of the article have compared the method of determining the coordinates of the location of the acoustic signal source using an artificial neural network with existing methods. In this method, the presence of a signal from the acoustic signal source at the reception points is determined by receiving and registering the signal at spatially separated points with known coordinates and further determining the difference in signal propagation times from the source to the signal reception points. The presence of a signal is determined by the middle of the area of the received signal. The number of signal reception points is set at the training stage of the artificial neural network according to the minimum error criterion in determining the coordinates of the acoustic signal source. The time differences of signal propagation from the source to the signal reception points are determined between all reception points, which are located in an orderly or random manner, and these time differences are fed to the input of a previously trained artificial neural network, at the output of which the coordinates of the acoustic signal source are obtained. The application of this method allows to determine the coordinates of the acoustic signal source without having prior information about the distance to the acoustic signal source or any other characteristics of the object, to determine the coordinates of non-periodic signals, to simplify the process of measuring time intervals and calculating coordinates
