Uhnder, a developer of digital imaging radar technology for automotive and next-generation mobility applications, will soon become the first company to mass-produce a fully automotive qualified, 4D digital imaging radar-on-chip.

The S80 is a fully integrated 77 GHz, 4D Imaging Radar-on-Chip (RoC) with Digital Code Modulation (DCM) certified for use in automotive safety applications, such as automatic emergency braking (AEB), lane keep assist, adaptive cruise control, and blind-spot detection, as well as automated driving functions, including autonomous vehicles.

Figure 1 shows “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.”  [2]

Automotive Qualification Milestones

In April 2022, Uhnder will release its S80 radar-on-chip to mass production. The device will be the first 4D digital imaging radar solution and will have completed stringent automotive requirements:

With these milestones completed, the automotive industry will be another step closer to improving road safety for all. [3]

Up until now, the most common radar technology for automotive has been Frequency Modulated Continuous Wave (FMCW) radar. More advanced Digital Code Modulation (DCM) radar has been used for military applications, but until recently it was too expensive for high volume production for automotive applications. 

As modern vehicles come packed with electronics such as radar and lidar for ADAS and autonomous driving, companies like Uhnder are emerging as essential suppliers of the components embedded in the products that Tier-1 suppliers, such as Magna, manufacture at scale for the world's automakers. [4]
