The Czech company Neuron Soundware has created the Sound Shield passive acoustic shield.
It turns sound into an air defense tool, according to Armadni noviny.
The war in Ukraine has shown that cheap drones are capable of paralyzing assets worth billions of euros.
European countries are actively seeking ways to protect thousands of kilometers of borders.
However, traditional active radars are economically unfeasible and often ineffective against modern threats.
“Every drone has its own specific acoustic signature, which our artificial intelligence can identify in real time and, using several sensors, determine its speed, altitude, and direction of movement,” the developers explain.
The Sound Shield system is based on fully passive sensors that do not emit any signals.
Therefore, the enemy cannot detect them or disable them using electronic warfare means.
The production cost of a single nEdge Mini sensor is only 100–150 euros, and its power consumption does not exceed 1 W.
They are deployed in a dense network along borders or around protected facilities.
The nEdge PRO computing module then collects data from surrounding microphones within a radius of up to 20 km and analyzes the sounds on-site using neural networks. If the artificial intelligence detects a threat, the data is instantly transmitted to a central database, where operators can see the drone’s exact flight path.
Last year, Ukraine also developed the ARes acoustic system for targeting drones and missiles.
