Uhnder developing the first digital automotive radar
Autonomous Vehicle Technology announces 2020 ACES Award Winner in Autonomy | Sensors category
Uhnder, a startup based in Austin, TX, that is working with Magna on its Icon radar technology, has come out of stealth mode to reveal the first digital automotive radar on chip (RoC), with evaluation modules delivered to AV companies in 2019 and production silicon planned for 2020. The RoC technology brings new capabilities for advancing vehicle safety and autonomy by leveraging advanced DSP concepts and coherent MIMO from the communications industry as well as the latest RF CMOS technology. The software-defined radar is said to be impervious to light and weather conditions and the most integrated radar sensing platform on the market. Digital signal and other radar computational processing is supported on chip with two floating point CPUs and two DSP engines. By using a large number of virtual receivers (the most on a single radar chip), the RoC achieves a claimed best-in-class angular resolution, giving radar the ability to identify two objects in close proximity—a weakness of conventional radar. Its digital code modulation (DCM) technology, based on similar CDMA technology used in cellular communications, enables a new generation of radar sensors capable of achieving new and unprecedented levels of performance—such as identifying a child about to dart out between two cars. This performance enhances the implementation of advanced safety features such as emergency braking and collision avoidance in today’s vehicles as well as the creation of tomorrow’s fully autonomous vehicles. It represents a significant advancement in AV radar technology with an approach that is cost-effective, scalable and open to future innovation.
