ra·dar

 (rā′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.
Idiom:
on (one's) radar/radar screen
In one's conscious awareness as a possibility or as an existing phenomenon: The governor said that running for president was not even on her radar screen.

[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)]

ra•dar

(ˈreɪ dɑr)

n.
1. a device or system for determining the presence and location of an object by measuring the direction and timing of radio waves.
2. a means of awareness; perception: lobbyists working under the media's radar.
[1940–45, Amer.; ra(dio)d(etecting)a(nd)r(anging)]

ra·dar

(rā′där)
1. A method of detecting distant objects and determining their position, speed, 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.
2. The equipment used in doing this.

radar

A radio detection device that provides information on range, azimuth, and/or elevation of objects.

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.
