Arbe Launches Alerion 4D Radar for Hard-to-Detect Drones

Arbe Robotics launched Alerion, a compact solid-state 4D imaging radar designed for counter-UAS systems and hard-to-detect drones. The Tel Aviv company says the system has been field-tested for defense applications and is being evaluated by counter-UAS integrators worldwide. Its 48Tx × 48Rx architecture creates 2,304 virtual channels to track FPV, mini, autonomous and fiber-optic drones through physical radar returns, including targets without radio-frequency control signals. Arbe says Alerion supports fixed, vehicle-mounted, portable and distributed deployments, with configurations covering 120° to 360° and integration for cameras and effectors.
