Arbe Expands into Defense and Homeland Security with the Alerion C-UAS Radar for Hard-to-Detect Drone Threats

The Compact, Low-Power 4D Imaging System Has Been Field-Tested and Is Now Under Evaluation by Integrators Worldwide

TEL AVIV, Israel, Sept. 14, 2026 /PRNewswire/ -- Arbe Robotics (Nasdaq: ARBE) (TASE: ARBE), a global leader in ultra-high-resolution radar solutions, today announced its entry into the counter-drone market with the Alerion C-UAS Radar, marking Arbe's expansion into defense and homeland security. This system is a compact ultra-high-resolution 4D imaging radar, designed to detect and track drone threats that are increasingly difficult for legacy counter-drone sensors to identify. These include FPV, mini, autonomous, and fiber-optic drones. Alerion has been successfully field-tested for defense applications and is currently being evaluated by counter-unmanned aircraft systems (C-UAS) integrators worldwide.

The global drone threat is escalating faster than the systems built to counter it. Inexpensive, low-signature drones increasingly threaten military and mobile defense operations, critical infrastructure, and public facilities. Low, slow, and small drones reflect very little radar energy, making them hard for legacy counter-drone sensors to spot, and furthermore, autonomous and fiber-optic-controlled drones fly with no radio link at all, so there is no signal to intercept. The Alerion ultra-high-resolution radar can detect the drone itself rather than its emissions, so it holds the track however the drone is controlled.

"Drone threats have become one of the most urgent security challenges worldwide, and detection of small drones is a current weakness where defenders are highly exposed," said Ram Machness, CEO of Arbe. "Alerion brings the highly detailed sensing capabilities Arbe has spent years developing for automotive - resolving small objects in dense clutter - to counter-drone defense in a compact platform designed for broad deployment. This opens a significant new market for Arbe."

Alerion is designed as an ultra-high-resolution sensing layer within multi-sensor counter-UAS architectures, holding the track continuously from first detection to minimum range. That includes the critical zone of a drone's final approach, where low-altitude flight, complex maneuvers, and ground clutter make threats hardest to follow. It separates drones from birds, vehicles, buildings, and vegetation, supporting reliable detection, low false-alarm rates, and precise cueing for the cameras and effectors that identify and engage the target.

Built on Arbe's ultra-high-resolution radar architecture, Alerion pairs that sensing with a solid-state design that is small, lightweight, low-power, and low-cost - the profile defense programs refer to as low SWaP-C (size, weight, power, and cost). This makes Alerion practical for fixed, vehicle-mounted, and portable systems.
