What is the Full Form of RADAR ?

RADAR - RAdio Detection And Ranging

RADAR is an electronic device that uses radio waves to determine the range of a particular object. The device was developed during the second world war, secretively by many countries. Apart for determining the range, Radars can also be used to determine the speed and direction of any moving object like an Aircraft.

How the RADAR works
The transmitter and receiver of a RADAR is located at the same place. When a transmitter sends radio waves, it hits back from all the objects in its path. The value of range speed, altitude and direction is calculated using these returning waves received by a receiver.

Applications of RADAR

  • Air traffic control
  • Antimissile and air-defense systems
  • Outer space surveillance
  • Aircraft anticollision systems
  • Flight control systems
  • Ocean surveillance systems
