4D imaging radar looks to advance ADAS and Level 5 automation
In contrast to cameras and LiDAR, 4D imaging radar uses echolocation and the principle of time-of-flight measurement to find things in its environment. It works well in all weather and environment conditions, including fog, heavy rain, and darkness. 4D imaging radar can tell when a car is moving and at what speed in a full white-out snowstorm. It also has the benefit of sensing out to 300 meters—a requirement for higher levels of automation.
