Radar Dish |

| Radar antennas, such as this one at London's Heathrow airport, enable air-traffic controllers to safely and efficiently direct airplanes in flight. The shape of the dish is designed to focus radar waves into a beam that scatters off aircraft. The part of the beam that gets reflected is detected by the radar dish and gives important information about the airplane, such as its altitude, heading, and speed. | ||||||
