Paywall article talks about 4D radar coming.
German Continental and San Jose, Calif., Xilinx are working to bring 4D imaging radar to production to support new-generation driver-assist systems and autonomous-driving vehicles.
4D radar can gauge relative speed, range and elevation allowing determination of height of a highway overpass. The companies say that by incorporating Xilinx's 16-nanometer system-on-chip technology, Continental's high-resolution radar sensor vision can be precise at 300 meters.
