Israel’s Arbe Robotics has announced its Lynx system, a surround imaging radar that processes 24 by 12 channels and is the only long-range, high-resolution, 360-degree sensing system available on the market. Arbe said Lynx outperforms the current industry 3 by 4 corner radars, and even the most advanced 12 by 16 front radars, which makes it the first surround radar “able to enhance perception and sensor fusion.”
The Lynx Imaging Radar’s small form factor and affordable price make it a highly suitable sensor for multiple installations around a vehicle, Arbe said. It was designed to complement Arbe’s flagship product, Phoenix Perception Radar, which processes 48 by 48 channels. Both radars can work in sync to deliver unified perception and interference avoidance. When Phoenix is combined with Lynx, the system can provide full sensor coverage around the vehicle, addressing different requirements in each position to enable safety for autonomous vehicles.
“Arbe is leading the radar revolution by creating new, enhanced products that push the limits of what radar is able to achieve,” said Kobi Marenko, CEO of Arbe Robotics. “For the first time, the industry is being introduced to surround imaging radar that enables true safety and the rollout of advanced autonomous applications. The launch of this new product represents a tremendous business opportunity for Arbe and for our Tier 1 partners.”
Arbe said there is a high demand for long-range surround sensors, with Lynx designed to be a corner and a back radar for L2+ and higher autonomous vehicles. In order to achieve true safety and autonomy, L2+ vehicles will need four to six surround imaging radars per vehicle, integrated on top of one or two perception radars, the company added. Lynx can be also used as a front radar for driver assist systems (ADAS), a new industry vertical for imaging radars, comprising several vehicles.
The company added that until now, 360-degree sensing has been performed with corner radars, which were used primarily for ADAS features such as blind spot detection, cross traffic alerting, and dynamic object tracking. But they fell short in providing a solution for more challenging use cases, such as alerting about a vehicle approaching from long distance, identifying stationary objects, detecting distance between one vehicle and the next, and measuring object shape and size, Arbe said. Because corner radars typically do not provide imaging, they were not integrated with other vehicle sensors for sensor fusion, nor contributed to the perception system.
Arbe said Lynx resolves a sensor gap for surround installations by providing a solution to challenging lighting and weather conditions that limit cameras and lidars, which also lack the long range needed.
“Corner radars cannot provide the needed redundancy to optic sensors because of their low resolution, and the high cost of the high resolution long range radars on the market makes them impractical to implement in multiple locations on a vehicle,” the company said. The Lynx Imaging Radar aims to be a reliable and affordable sensor that provides redundancy and data diversity needed to roll out autonomous functionality. Effective sensing can be done in all environmental conditions, and gather data that optical sensors lack, including velocity, long range, depth perception, and more, the company said.
