radar
意味: A detection system that transmits radio waves and analyses their reflections to determine the range, angle, and velocity of objects such as aircraft, ships, and weather formations.
Radar was pivotal in the Battle of Britain and has since become indispensable in air traffic control, weather forecasting, maritime navigation, and speed enforcement. The technology can penetrate clouds, fog, and darkness, giving it advantages over optical systems. Figuratively, 'on the radar' means something has come to attention, while 'under the radar' means it has gone unnoticed.
