RADAR is an acronym of ra(dio) d(etection) a(nd) r(anging) which was coined by Lieutenant-Commander Samuel M. Tucker and Lieutenant-Commander F. R. Furth of the United States Navy in November 1940. The verb is probably derived from the noun.
Meanings
-
(uncountable) In full primary radar: a method of detecting a distant object and determining its position, velocity, or other characteristics by analysing radio waves (usually microwaves) which are sent towards the object and which reflect off its surfaces; also, the field of study of this method.
Although operational environments profoundly differ, both kinds of autonomous vehicles, groundcraft and aircraft, will still rely on conceptually the same sorts of sensors — cameras, radar and lidar — to perceive surroundings in real time.
2020 January 1, Adam Hadhazy, “Achieving autonomy”, in Aerospace America, archived from the original on 22 Apr 2025:They were able to find the enemy fleet using radar.
- (broadly, uncountable) In full primary radar: a method of detecting a distant object and determining its position, velocity, or other characteristics by analysing radio waves (usually microwaves) which are sent towards the object and which reflect off its surfaces; also, the field of study of this method. ▸ In full secondary radar: a method of detecting a distant object and determining its position, velocity, or other characteristics by analysing signals transmitted by the object in response to radio waves sent towards the object.
-
(countable) In full primary radar: a method of detecting a distant object and determining its position, velocity, or other characteristics by analysing radio waves (usually microwaves) which are sent towards the object and which reflect off its surfaces; also, the field of study of this method. ▸ Often preceded by a descriptive word: a system using one of the above detection methods, differentiated by configuration or platform, frequency, power, and other technical attributes.
Evidence as to the audio monitor's reading is required to prove the [police] officer used the radar unit properly, and must be shown in order to secure a conviction for speeding when using radar.
2002, Brian Jonathan Wolk, “Producing Inconsistencies in Various Cases”, in Ohio Traffic Tickets are for the Birds: A Practical Defense Manual for Juveniles and Adults, Lincoln, Neb.: Writers Club Press, iUniverse, →ISBN, section 4 (Producing Inconsistencies), page 145:The Ministry of Defence funded the development of an entirely new radar and improved avionics.
-

- (broadly, uncountable) Often preceded by a descriptive word: a natural (for example, in an animal such as a bat) or human-made detection method based on the analysis of reflected signals other than radio waves, as light waves or sound waves; (countable) an instance of this.
-
(countable, figuratively) A superior ability to detect something; an awareness, an intuition.
His sensitive radar for hidden alliances keeps him out of trouble.
It [a goal] came inside 50 minutes and moments later [Edinson] Cavani should have had a 12th. [Paul] Pogba and [Luke] Shaw combined before the left-back's cross teed up the striker but his radar was awry.
