Arbe Robotics Ltd. introduces the addition of Free Space Mapping to its revolutionary Imaging Radar perception stack at CES 2022. Arbe has radically enhanced its solution with an algorithm that identifies the drivable sections in the environment surrounding the vehicle, while aggregating a map of the environment, and localizing the vehicle within this map. This is the first time an automotive radar is able to contribute to free space mapping, a critical function of autonomous driving that requires great accuracy and redundancy.

The Imaging Radar complements camera sensors with its ability to sense Doppler - the direction and velocity of moving objects, at long range and wide field of view, sensing the environment in all weather, lighting, and visibility conditions. The inability of traditional automotive radars to perform Free Space Mapping posed a significant problem to OEM's perception teams, who had to rely solely on camera algorithms. Arbe's perception Imaging radar is providing true sensor fusion that leverages the advantages of each of the individual sensors, making it an imperative component in any perception stack. The Free Space Mapping feature of Arbe's perception imaging radar, senses the unobstructed space in the environment around the vehicle. To yield the representation of the drivable space, Arbe's radar analyzes ultra high-resolution data in all dimensions, that stems from all the targets in the field of view --  pedestrians, vehicles, buildings, trees, and more.
