Counter-Drone Sensing
Coverage from Militarnyi, The Defense News, and others
Counter-drone sensing combines active and passive technologies to identify small aircraft, follow their movement, and distinguish them from birds, vehicles, buildings, vegetation, and other clutter.
Arbe Robotics’ Alerion uses high-resolution 4D imaging radar to detect drones that may lack usable radio emissions, including fiber-optic-controlled systems, while Aaronia’s AARTOS HAWK T1 uses passive radio direction finding and Blind TDoA geolocation. Related systems such as Robin Radar Systems’ IRIS On-The-Move adapt detection for vehicles, vessels, ports, and coastal environments. Together, these technologies provide the observation layer for counter-UAS operations across fixed, mobile, airborne, and maritime settings.
