Arbe launches Gryphon 4D radar for unmanned ground vehicles

Arbe Robotics has launched Gryphon, a solid-state 4D imaging radar for unmanned ground vehicles operating on rough terrain. Announced on 19 October 2026, the system combines 48 transmit and 48 receive channels to generate a dense radar point cloud for detecting obstacles and mapping areas a vehicle can traverse. Arbe is targeting logistics, agriculture, mining, industrial and defence vehicles.

Gryphon is designed to identify rocks, vegetation, debris and barriers, alongside negative obstacles such as holes, ditches and washouts. Arbe says the radar data supports free-space mapping, tracking, odometry and localisation where satellite navigation is unavailable. Its intended operating conditions include dust, smoke, fog, rain, snow and darkness, with radar observations supplying input to the vehicle’s navigation and perception systems.

The hardware builds on Arbe’s automotive-grade radar architecture and perception algorithms. A solid-state design with no moving scanning elements is intended to simplify integration, while support for extended data cables allows sensors to be positioned around different vehicle shapes. The company describes configurations spanning small UGVs and large industrial vehicles, with applications including driver assistance, leader-follower operation and autonomous navigation.

Arbe’s earlier automotive and robotaxi work provides the chipset and high-channel-count sensing foundation for the new system. Its first-quarter 2026 update reported follow-on Phoenix radar orders from robotaxi customers and initial chipset shipments to Hirain. Gryphon packages that radar technology into a system for ground vehicles negotiating unstructured terrain.
