Ansys and Oculii Reimagine Automotive Radar Systems

Using Ansys simulation solutions, Oculii is developing artificial intelligence (AI) software and hardware for radar systems that will allow autonomous vehicles (AVs) to more accurately perceive their surroundings. The company relies on Ansys for its predictive accuracy, driving more refined design optimizations that shorten design cycles and support Oculii's mission of enabling high performance perception at lower cost.

Commercial radar systems have long been hampered by a simple design tradeoff: improving resolution requires more antennas, which increases size, cost and power. This is a significant problem for AVs that need to perceive any environment with a high degree of accuracy to operate safely. AVs compensate for poor radar resolution by employing a suite of various sensors, which increases system complexity and cost. Oculii's technology unlocks the full potential of commercially available radar, using AI to learn and adapt to the environment, increasing resolution by up to 100X.

Ansys HFSS helps Oculii evaluate and optimize key elements of radar transmission, including antenna and sensor placement and performance, with a predictive accuracy of 80 to 90 percent — improving overall design speed. This enables compact radar technology that offers superior resolution through low-cost, mass-manufacturable hardware.

“The way to improve radar technology is through software, because software fundamentally improves with data,” says Steven Hong, CEO at Oculii. “Ansys HFSS has been invaluable because it allows us to make high-fidelity measurements and predictions around how design optimizations will impact real world performance. Using HFSS, we can close design cycles more quickly, and build confidence in what we do. We have also been impressed by Ansys' support team — they helped us overcome a number of challenges to get the most out of the solution, which helps us get the most out of radar systems.” 

Driven by consumer demand for active safety features and other self-driving technologies, the global automotive radar market is estimated to reach $12.5 billion by 2026 according to industry research. Radar is a key enabler for AVs and advanced driver assistance systems (ADAS). Radar's advantages lie in its superior range, and the ability of its radio waves to pass through rain drops, snow and fog. 

“AVs face immense engineering challenges before they'll be deemed safe,” says Shane Emswiler, senior vice president of products at Ansys. “There is great demand within the market for higher-performing, cost-effective autonomous technology. Our collaboration with Oculii enables us to facilitate solutions that will define autonomous radar technologies of the future.”
