Arbe launches ‘the most advanced radar antenna in the market’
Autonomous Vehicle Technology announces 2020 ACES Award Winner in Autonomy | Sensors category
Arbe launched at IAA 2019 what it claims is the first radar antenna designed to protect pedestrians by detecting fast-moving or stationary objects at long range, in daylight or at night, and in bad weather conditions. The company says its Phoenix product is the densest antenna array available, has the largest number of channels, widest field of view, and highest resolution on the market—paving the way for enhanced safety by detecting people separately from the sidewalk or roadside. The company adds that the radar features low power consumption per channel and the highest sensitivity. Field-test results on steep and curving roads and sidewalks show the ability to detect small objects like pedestrians, bicycles, and motorcycles; large vehicles of all sizes; and stationary objects like guardrails, road obstacles, and parked cars—in daylight or darkness and in rain, fog, or snow. At 14 x 11 cm (5.5 x 4.3 in), the antenna can be integrated within the vehicle envelope designed for basic radar units, receiving and transmitting 96 channels. Its small size is important to automakers because it’s aesthetically pleasing to car owners, as the radar can be hidden behind the grill or headlight. Other pedestrian-friendly specs include high resolution at 1-degree azimuth and 2-degree elevation, which is believed to be an industry first; a wide field of view at 100- to 140-degree azimuth and 30-degree elevation; and a range currently at 250 m (820 ft) projected to reach 400 m (1310 ft) in future releases. The system allows OEMs to meet stricter safety standards and raise ADAS levels for new revenue-generating features like, most importantly, pedestrian and cyclist safety. That last concern is addressed with low false-alarm rates.
