description: The object of study is an acoustic camera The aim of the work is to develop an algorithm for estimating the direction to a highâfrequency sound source This work is devoted to the development of an algorithm for estimating the direction of a directional signal source in the ultrasonic and audible range using the methods of determining the direction of Beamscan, MVDR and MUSIC. In the course of the study, the following were developed: 1. An algorithm for estimating the direction of high-frequency sound waves to a source 2. The algorithm for receiving data from the microphone array of the layout 3. Algorithm of digital processing of the incoming signal and transformation into the form of complex data for further application of localization methods 4. Sound localization algorithm The entire algorithm was also tested and the methods were compared at ultrasonic and audible frequencies. As a result of the work, an algorithm has been developed that is able to determine the direction of sound in the direction based on data from the acoustic camera layout at frequencies from 0 to 80 kHz. Open educational resources and information search and analysis programs were used. Python software is used.
