ra·dar (r  där)n. 1. A method of detecting distant objects and determining their position, velocity, or other characteristics by analysis of very high frequency radio waves reflected from their surfaces. 2. The equipment used in such detection. [ra(dio) d(etecting) a(nd) r(anging).] |
radar [ˈreɪdɑː]
n
1. (Electronics) a method for detecting the position and velocity of a distant object, such as an aircraft. A narrow beam of extremely high-frequency radio pulses is transmitted and reflected by the object back to the transmitter, the signal being displayed on a radarscope. The direction of the reflected beam and the time between transmission and reception of a pulse determine the position of the object Former name radiolocation
2. (Electronics) the equipment used in such detection
[C20 ra(dio) d(etecting) a(nd) r(anging)]
| radar (rdär) 1. A method of detecting distant objects and determining their position, speed, material composition, or other characteristics by causing radio waves to be reflected from them and analyzing the reflected waves. The waves can be converted into images, as for use on weather maps. |   A radio antenna sends out a stream of radio waves (light gray). When they reach the airplane, they bounce off of it and send reflected waves (dark gray) back to a receiver in the antenna. The reflected waves are then processed electronically and analyzed to determine the airplane's distance, speed, and position. An image of the airplane is sometimes also generated. |
radar
an acronym for RAdio Detecting And Ranging: a method and the equipment used for the detection and determination of the velocity of a moving object by reflecting radio waves off it.
