Uhnder Brings 4D Digital Imaging Radar-on-Chip to Mass Production

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

The S80 is a fully integrated 77 GHz 4D imaging Radar on a Chip (RoC) with Digital Code Modulation (DCM) certified for use in automotive safety applications, such as Automatic Emergency Braking (AEB), lane-keeping assist, adaptive cruise control, and blind-spot detection, as well as automated driving features, including self-driving vehicles.

The RoC uses a phase modulated continuous wave (PMCW) and multiple input multiple output (MIMO) radar architecture capable of processing up to 192 virtual channels. It supports 12 transmit (Tx) antenna channels and 16 receive (Rx) antenna channels. The S80 is fully software-defined, has onboard processors to run on-chip algorithms, and can also enable optimization with deep learning neural networks and artificial intelligence (AI) found in computer systems. most advanced automated perception.

The device’s DCM minimizes mutual interference from neighboring radars and provides high contrast resolution (HCR) providing maximum discrimination as well as high confidence detection of independent targets, including vulnerable road users (VRUs) , such as pedestrians and cyclists, in long-range (LRR), medium-range (MRR) and short-range (SRR) radar 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. Vulnerable road user fatalities now account for 20% of all road fatalities in the United States and even more in developing countries. ADAS technologies, such as Automatic Pedestrian Emergency Braking (P-AEB) that can operate reliably at night, can help reduce pedestrian fatalities according to the latest report from the Insurance Institute for Highway Safety . Improved high-resolution perception sensors, such as Uhnder’s on-chip radar, can potentially help reduce this rising category of fatalities.

Uhnder’s technology offers the industry’s first digital radar solution with improved accuracy and the ability to detect moving or standing objects, large or small, at short and long ranges, in all weather and conditions. lighting, while mitigating mutual interference between other radars. Uhnder’s digital radar can clearly identify a pedestrian crossing the road, a child entering the street next to a parked car or a cyclist next to a guardrail, at levels of accuracy than analog radar systems traditional can not achieve.

Digital radar delivers 16x better resolution, 24x more on-target power and 30x more contrast than today’s analog offerings, improving detection capabilities for better road safety for all users – drivers , passengers, cyclists and pedestrians. As more radars are installed on vehicles and other mobility solutions, interference between adjacent radars becomes a problem. Our radar, based on digital code modulation, alleviates this problem.

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

• Automotive Electronics Council (AEC) Q104 qualification

• ISO 26262 Automotive Safety Integrity Level (ASIL-B)

• Production Part Approval Process (PPAP) with its first Tier 1 automotive customer, Magna

Uhnder’s on-chip radar, used in Magna’s ICON digital radar, will debut on vehicles in 2022.
