Fravek
Fravek is developing passive radar technology that detects and tracks low-flying drones by using ambient radio signals already present in the environment, without transmitting any radar signal of its own. The system connects multiple sensing nodes to build a unified air picture, with software being developed to classify detections and deliver useful tracks to operational security systems. The company is targeting field testing in Ukraine and at Swedish pilot sites by Q4 2026.

Problem
Drone threats can approach critical infrastructure and defense sites beyond the reach of perimeter security systems, creating a dangerous blind spot. These low-flying threats often slip between traditional air defense systems and ground-level security, leaving operators without adequate early warning or time to prepare a response.
Solution
Fravek is developing passive radar technology that detects and tracks low-flying drones by using radio signals already present in the environment, without transmitting any radar signal of its own. The system leverages reflections from these existing signals across connected sensing nodes to classify detections and combine information into a unified air picture. This approach provides an additional layer of awareness for operators, closing the gap between air defense and perimeter security. The technology is designed to deliver useful tracks to operational security systems, enabling earlier warning and more time to respond to approaching drone threats.
Target Audience
Primary customers are critical infrastructure operators, system integrators serving those operators, and defense and government programs that need low-airspace drone detection capability.
