Uhnder and dSPACE co-operate to develop radar technology 20th April

As radar systems are a key technology for automated and autonomous driving Uhnder and dSPACE have agreed to cooperate to ensure that the developments in radar sensor technology can keep the pace with the high safety requirements in traffic.

Both companies will support each other in the continuous development of sensors and validation solutions.

To meet the high requirements for safety and quality, radar sensors must detect their surroundings reliably and in great detail. For road use, it is important to implement robust measures that minimize interference and disturbance signals. To do this, Uhnder has developed a unique digital Radar-on-Chip (RoC), using a combination of advanced CMOS and Digital Code Modulation (DCM) technology.

Uhnder's 4D digitally modulated radar chip offers groundbreaking performance by integrating 192 virtual channels onto a single chip and pioneers High Contrast Resolution (HCR), which provides significantly improved range and angular resolution and makes it possible to separate small radar reflectors from proximate large reflectors. Throughout the development process, Uhnder relies on dSPACE Automotive Radar Target Simulators to subject sensors whose signals are processed using this modulation method to the most realistic tests possible until the sensors are approved for series production.

“Digitally modulated radar signals offer significant advantages in ADAS and AD applications. The radar test solutions from dSPACE made it easy for us to investigate interferences between radar systems and to advance our systems as realistically as possible,” said Ralf Reuter, Senior Director of Customer and Application Engineering at Uhnder, about the initial results of the collaboration.

Senior Product Manager Dr. Andreas Himmler from dSPACE added: “The cooperation with Uhnder provides us with new requirements in sensor development directly and timely. This gives us a headstart in the development of suitable concepts for particularly reliable validation. This applies particularly to the fulfillment of our customers' challenging requirements with regard to radar target simulation.”
