It is an enhanced digital radar solution with better accuracy and power to sense different objects at any distance in all weather conditions

The SA80 will soon become the first mass-produced, fully automotive qualified, 4D digital imaging radar-on-chip that will transform our roadways, making possible next-generation advanced driver assistance systems (ADAS), autonomous vehicles (AVs) and automated mobility applications.

“Uhnder’s 4D digital imaging radar-on-chip is a next-generation product that demonstrates new ways to advance automotive safety to save lives,” said Douglas Campbell, president, Automotive Safety Council. “Fatalities of vulnerable road users are now 20 per cent of all roadway deaths in the US and even more in developing countries. ADAS technologies, such as pedestrian automatic emergency braking (P-AEB) that can reliably operate at night, can help reduce pedestrian fatalities.” 

The SA80 is an enhanced digital radar solution with better accuracy and the power to sense moving or standing objects, large or small, at both short and long distances in all weather and lighting conditions, all while mitigating mutual interference between other radars. 

Uhnder’s digital radar can clearly identify a motorcycle between two trucks, a pedestrian crossing the road, a child entering the street from beside a parked car, or a bicyclist next to a guard rail, at levels of accuracy that legacy analog radar systems cannot achieve.

The digital radar can identify a pedestrian crossing the road, a child entering the street from beside a parked car, or a bicyclist next to a guard rail, at levels of accuracy that legacy analogue radar systems cannot achieve.

“Digital radar provides 16 times better resolution, 24 times more power on target, and 30 times better contrast than today’s analogue offerings, improving detection capabilities for better road safety for all users – drivers, passengers, cyclists, and pedestrians,” said Manju Hegde, CEO and cofounder, Uhnder, Inc. “As more and more radars are fitted onto vehicles and other mobility solutions, interference among adjacent radar becomes problematic. Our radar, based on Digital Code Modulation, mitigates this problem.”

The device meets stringent automotive requirements including:

  • Automotive Electronics Council (AEC) Q104 qualification
  • ISO 26262 Automotive Safety Integrity Level (ASIL-B) rating
  • Production Part Approval Process (PPAP) with its first Tier 1 automotive customer, Magna

With these milestones, the automotive industry will be another step closer to improving road safety for all.

Uhnder’s radar-on-chip will debut in vehicles in April 2022.
