The Drone Radar initiative has launched an open-source acoustic detection network that utilizes volunteer Android smartphones to identify and track Shahed-type drones across the Baltic region and Poland.

Key Points

• Volunteers place powered, window-facing Android phones running the Drone Radar app to monitor for specific low-frequency drone engine signatures.
• The system triangulates drone locations by cross-referencing acoustic data collected from multiple nearby devices in the network.
• The project is led by the startup Mainline in collaboration with the Lithuanian Artificial Intelligence Association and the Baltic Institute of Technology.
• Organizers aim to recruit 10,000 active participants to establish the largest civic acoustic drone detection network in the Baltic states.
• Future expansion plans include integrating audio from residential surveillance cameras and installing sensors on telecommunications towers.

Why it Matters

This crowdsourced approach creates a scalable, low-cost security layer that enhances regional situational awareness against aerial threats. By leveraging existing consumer hardware, the initiative demonstrates a new model for civic-led defense technology and public-private cooperation in national security.
