ChSU: Microphone system for recognizing drones by sound

2023: Product Announcement

In Russia, they created a microphone system for recognizing drones by sound within a radius of 1 km. This is the development of specialists from Cherepovets State University (ChSU). It became known at the end of August 2023.

According to the press service of the operator of the NTI Platform acceleration programs, the system is a hardware and software complex consisting of a microphone matrix and artificial intelligence. Microphones monitor the acoustic situation and transmit information about the surrounding sounds to a computer, where they are processed by a neural network algorithm. During analysis, AI is able to select the sound of a flying drone and determine the distance and direction to it.

One of the developers of the module, a graduate of the Department of Cyber ​ ​ Physical Systems Nikita Efimov explained to Gazeta.Ru that by the end of August 2023, drones are monitored by passive means (video cameras and thermal imagers) and active ones (radio direction finders). However, they, according to the specialist, have disadvantages.

For example, visual analysis systems are large, and active schemes find themselves on the air, in connection with which the observed object can go into radio silence or harm the search engine, - said Efimov.

The sound module, developed by specialists of Cherepovets State University, cannot be detected, since it does not emit signals. It is also capable of working in complete darkness and has smaller dimensions, Efimov said.

Testing of the new system is expected to begin before the end of 2023. Based on the results of experiments, its accuracy and effectiveness will be determined. However, by the end of August 2023, preliminary estimates show that the matrix is capable of detecting objects within a radius of up to one kilometer with an accuracy of 94%.^[1]
