Infineon, Oculii join forces on automotive radar
Imaging radar technology developer Oculii (Dayron, OH) and Infineon are collaborating on radar software systems that scale performance for cost-effective single chip implementations tailored for Level 1 ADAS, all the way to multi-chip high performance systems tailored for Level 4 autonomous driving.

A fundamental building block for both current and future automated driving applications, radar sensors are used in distance warning and automatic emergency braking systems – making driving safer. Such sensors will be part of the standard equipment of every new car in the future. Among other things, they are required for autonomous driving. With more than 100 million 77 GHz radar chips sold, Infineon is the technology and market leader in this segment.

Traditional radar architectures require more physical antennas in order to deliver higher angular resolution, but additional antennas translate into higher cost, size, and power. Proprietary Virtual Aperture Imaging radar software, developed by Oculii, increases the angular resolution of an array through sophisticated software as opposed to more physical transceiver elements. This software technique uses an array multiplier – enabling a MIMO radar sensor to achieve an increase of over 10x in angular resolution, delivering sub-degree angular with existing mass manufactured automotive-grade silicon.

The partnership will enable automotive OEMs and Tier-1 customers to leverage Infineon’s best in class chipset containing AURIX™ MCUs, MMIC and power supply hardware platform along with Oculii’s Virtual Aperture Imaging software to deliver high-resolution performance at an attractive price point.

“This partnership is another step by Infineon to leverage advanced software around our best in class 77 GHz radar portfolio,” said Ritesh Tyagi, Head of the Automotive Silicon Valley Innovation Center at Infineon. “Oculii’s Virtual Aperture Imaging technology combined with Infineon’s existing mass manufactured automotive grade radar solutions enables an increase in angular resolution without the need for multiple active transceivers or expensive antenna technologies.”

“Infineon is the technology and world market leader in radar silicon, and we have been working closely with them to integrate our Virtual Aperture Software to further improve the angular resolution and performance of their market leading radar sysyems,” said Oculii’s CEO, Steven Hong, PhD. “Our team has demonstrated that our software architecture can improve angular resolution and field
