Radar 雷达

Long-range radar antenna, used to track space objects and ballistic missiles.Radar of the type used for detection of aircraft. It rotates steadily, sweeping the airspace with a narrow beam.

Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar transmits radio waves or microwaves that reflect from any object in their path. A receive radar, which is typically the same system as the transmit radar, receives and processes these reflected waves to determine properties of the object(s).
