How does a radar work? Introduction, what it is for


post-title

Let's see how a radar works, what it is used for and use of this instrument by airport personnel, to ensure the safety of all flights in transit.


Introduction to how a radar works

A radar serves to show the exact position of an airplane, especially during take-off or landing.

Flight controllers can thus assist the pilot to carry out delicate maneuvers without any danger.


Special radar transmitters installed at the airport send signals consisting of radio waves to the aircraft.

These signals bounce off the plane and return back to the transmitter, in order to provide the exact position.

The signals are processed by forming accurate drawings that describe the exact point where the plane is located at that time.

The origin of the term "RADAR" dates back to 1940, used by the US Navy as an acronym for the English "radio detection and ranging" which means "detection and measurement of distance by radio".

Over time, the acronym has become part of the English language as well as many other languages, becoming a term commonly used in the navy and aeronautics.
