Belarus has unveiled the "SKANER 2.1" acoustic system, designed to detect FPV drones and other unmanned aerial vehicles, including those controlled via fiber optics. Such targets are difficult to identify using traditional radio monitoring, so the developers focused on analyzing the acoustic signal.

The new generation system was developed by specialists from "InnoTech Solutions". The complex creates a detection and direction-finding zone for quadcopters with electric motors, and when working in conjunction with elements of the ALS "Skaner" complex, it can detect aircraft-type drones, determining their speed and flight path.

The development is intended for use by mobile groups to protect objects and personnel. The device has a diameter of 23 centimeters and an assembled weight of 1.2 kilograms. The system can be deployed in less than two minutes.

The detection range for FPV drones is from 100 to 300 meters, depending on the acoustic environment. The system can detect drones with internal combustion engines at a distance of up to 1.5 kilometers.

"SKANER 2.1" uses artificial intelligence algorithms that filter out extraneous noise and identify the characteristic acoustic signature of FPV drones. Target notifications are sent to the operator not only on the main screen but also on a smartphone and smartwatch. The complex can operate autonomously for up to 12 hours on its built-in power source.
