Everything about Radar

Object detection system using radio waves

Radar is a system that uses radio waves to determine the distance (ranging), direction, and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations and terrain. The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term radar has since entered English and other languages as an anacronym, a common noun, losing all capitalization. Wikipedia →

📖 Definitions

Noun 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.

Noun 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.

Noun 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.

Noun An installation of the apparatus for operating one of the above detection systems.
