Lithuanian startup launches open-source network to detect Shahed-type drones

Drone Rada (Dronuradaras.lt) uses Android phones as passive acoustic sensors to detect Shahed-type drones via low-frequency engine signature analysis. Multiple nearby devices cross-correlate signals to triangulate position, feeding a public real-time map. The initiative targets 10,000 volunteers across the Baltics and Poland, with plans to add surveillance camera audio and telecom tower-mounted sensors.
