ANSYS revolutionizes radar simulation for AVs
Autonomous Vehicle Technology announces 2020 ACES Award Winner in Autonomy | Simulation category
The best radar simulation technologies based on the physics of electromagnetic scattering have not been fast enough to provide engineers with accurate data to complete designs. Interpreting radar signals that may be arriving simultaneously from many different reflecting points is a difficult simulation task. However, Accelerated Doppler Processing simulation technology within the ANSYS HFSS SBR+ simulation package is set to revolutionize the way automotive companies design and predict the safety and performance of radar systems in AVs without performing physical testing. Using a patent-pending simulation algorithm that speeds up the simulation of radar sensors in complex traffic situations, it enables engineers to test vastly more traffic scenarios with full-physics fidelity than would ever be possible by driving instrumented automobiles on existing roadways. More importantly, Accelerated Doppler Processing makes it possible to accurately test “corner cases”—involving potentially fatal driving scenarios—in a safe, virtual environment. With Accelerated Doppler Processing, engineers can now use reduced-order models just to identify especially interesting or difficult corner cases. Full-physics simulations typically take large amounts of time and processing power, but Accelerated Doppler Processing enables engineers to do a lot of simulation in a much shorter timeframe. The new algorithm is 500-times faster than the previous one. A traffic scenario that used to take a week to solve using multiple cores in the cloud can now be run dozens of times in a single day. Accelerated Doppler Processing could make the extensive testing of all traffic scenarios possible in a few years’ time, instead of the hundreds of years needed for physical road testing.
