ra·dar

(rā′där)

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.

radar

(ˈreɪdɑː)

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

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.
