Arbe Robotics Pivots to Defense with Alerion Drone-Detection Radar

The rise of inexpensive, small-scale drones has outpaced current defense capabilities. Many modern unmanned aerial vehicles operate without radio links or emit minimal radar signatures, rendering traditional interception methods ineffective. Alerion addresses this gap by tracking the physical object rather than relying on signal interception. By leveraging high-resolution sensing originally developed for automotive applications, the system maintains continuous tracks through complex environments, distinguishing drones from birds or ground-level clutter.

CEO Ram Machness notes that the platform is designed for broad deployment, balancing performance with low power and weight requirements. This profile allows for integration into fixed, portable, or vehicle-mounted architectures. As the company moves to capture a share of the homeland security market, it plans to showcase the radar's performance during the upcoming Counter UAS Homeland Security Europe conference in London.
