What Is Single 4D Imaging Radar?
Single 4D Imaging Radar is an integrated radar technology that combines RF front-end circuits, digital signal processing, and 4D imaging capabilities on a single CMOS chip.
Unlike conventional millimeter-wave radar systems that primarily provide range and azimuth information, 4D imaging radar simultaneously detects range, velocity, angle, and elevation. This enables the generation of high-resolution point-cloud information for advanced automotive perception.
The technology is being developed for corner-radar and forward-radar applications within ADAS and autonomous-driving platforms. Its compact architecture, lower power requirements, all-weather performance, and ability to generate detailed environmental information are supporting its adoption in next-generation vehicles.
