Arbe launches new high-density automotive radar antenna
Arbe announced today the launch of what the company is saying 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 any weather conditions. The company is claiming that its new Phoenix High-density Antenna is "the densest antenna array available, with a form factor designed to perfectly fit automakers’ current specifications." The company adds that the radar antenna has "the largest number of channels, widest field of view, and highest resolution on the market," paving the way for enhanced safety due to the unit's ability to detect people separately from the sidewalk or roadside.
Arbe says that field-test results on steep and curving roads and sidewalks show that the Phoenix High-density Antenna is able to detect both small objects like pedestrians, bicycles, and motorcycles, and large objects like vehicles of all sizes, as well as stationary objects like guardrails, road obstacles and parked cars, whether in daylight or darkness and in rain, fog, or snow. The company adds that the radar features the highest resolution, low power consumption per channel, and the highest sensitivity.
At 14-by-11 centimeters, the Phoenix High-density Antenna is designed for integration within the space currently designed for basic radar units in vehicles. The system reportedly utilizes the full space, receiving and transmitting 96 channels, eliminating the common problem of false alarms. In achieving that optimal form factor, the Arbe antenna has, "surpassed a critical technological milestone. Size is important to automakers also because it’s aesthetically pleasing to car owners, as the radar is hidden behind the grill or headlight."
Other key features that reduce the risk to pedestrians include high resolution at 1-degree azimuth and 2-degree elevation—which is believed to be an industry first; a wide field of view (FoV) at 100 to 140-degree azimuth and 30-degree elevation; and a range currently at 250 meters and projected to reach 400 meters in future releases.
According to Arbe CEO Kobi Marenko, the Phoenix radar system is a vital addition to the sensor suite that vehicles with high standard of safety require. “OEMs today are challenged to meet stricter safety standards set by the New Car Assessment Program, and they’ll need to raise their ADAS levels without compromising safety. This opens the door to new revenue-generating features like autonomous emergency steering and braking, adaptive cruise control with autonomous lane changes, and, most importantly, pedestrian and cyclist safety. Our imaging radar is the first in the industry to address all of these concerns—and with a revolution in the false alarms rate, a major concern for automakers.”
