Arbe Expands into Defense and Homeland Security with the Alerion C-UAS Radar for Hard-to-Detect Drone Threats
Arbe launches its Alerion 4D imaging radar to address hard-to-detect drone threats and enter the counter-UAS defense and homeland security market.
Rhea-AI Summary
Arbe Robotics (ARBE) announced entry into the counter‑drone market with its Alerion C‑UAS Radar, expanding its focus into defense and homeland security applications as of September 14, 2026.
Alerion is a compact, ultra‑high‑resolution 4D imaging radar designed to detect and track difficult drone threats such as FPV, mini, autonomous, and fiber‑optic‑controlled drones. The system has been successfully field‑tested for defense uses and is now under evaluation by counter‑UAS integrators worldwide. Built on Arbe's automotive radar architecture, Alerion provides continuous tracking from first detection to minimum range, separates drones from birds and clutter to support low false‑alarm rates, and offers a solid‑state, low‑SWaP‑C design suitable for fixed, vehicle‑mounted, and portable systems.

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

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
What specific drone threats is the Alerion C-UAS Radar designed to detect?
Alerion is designed to detect and track hard-to-spot drones including FPV, mini, autonomous, and fiber-optic-controlled drones. The radar detects the drone itself rather than relying on radio emissions, so it can maintain a track regardless of how the drone is controlled.
How does Alerion improve detection compared with legacy counter-drone sensors?
The Alerion ultra-high-resolution radar detects low, slow, small drones that reflect little radar energy and are difficult for legacy sensors to spot. It separates drones from birds, vehicles, buildings, and vegetation to support reliable detection, low false-alarm rates, and precise cueing for cameras and effectors.
In which counter-UAS architectures is Alerion intended to be used?
Alerion is designed as an ultra-high-resolution sensing layer within multi-sensor counter-UAS architectures. It holds the track continuously from first detection to minimum range, including the drone's final approach zone where low altitude, complex maneuvers, and ground clutter make threats hardest to follow.
What deployment options does the Alerion C-UAS Radar support?
With its solid-state, small, lightweight, low-power, and low-cost (low SWaP-C) design, Alerion is described as practical for fixed installations, vehicle-mounted systems, and portable counter-UAS solutions.
Where can interested parties learn more or see Arbe present Alerion?
More information is available on the Alerion C-UAS Radar product page. The company also invites interested parties to meet its team at Counter UAS Homeland Security Europe, taking place September 23–24, 2026, in London.
