Radio (or Radiation) Detection and Ranging, a.k.a. RADAR is a detection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of objects relative to the site. The modern uses of radar are highly diverse, including air and terrestrial traffic control, radar astronomy, air-defense systems, antimissile systems, marine radars to locate landmarks and other ships, aircraft anti-collision systems, ocean surveillance systems, outer space surveillance and rendezvous systems, meteorological precipitation monitoring, altimetry and flight control systems, guided missile target locating systems, self-driving cars, and ground-penetrating radar for geological observations. Radar is an important sensor in the autonomous cars. Typically, an autonomous car will have Lidar to scan the environment, Radar to identify the objects and Sonar to hear the objects. In our video of Tesla Model 3, we saw that the Forward-looking Radar is the primary sensor used to detect th
