RADAR: Radio Detection And Ranging

RADAR is an abbreviation of Radio Detection And Ranging. It is an electronic device which detects objects by using ultra-high frequency or microwave segment of the radio frequency spectrum to control the location of the spot or range of an object. It can also be used to discover or spot the speed and regulation of an operational object.

Throughout the Second World War, it was covertly designed and created by many countries. In 1940, the term RADAR was specified by the United States Navy.

Working of RADAR

RADAR operates by sending an electromagnetic pulse, transferred through the surrounding. On the track of pulse, objects which are known as targets will disperse almost all the energy but few will be diverted back to the RADAR. If the targets then dispersed signals merge to create a powerful signal as dispersed radiation will go to the receiver. The worth of range, position, direction, and altitude is measured by these dispersed signals.

Usage of RADAR

  • Radar is used to decide the target position in the military.
  • Radar is used to notify and alert aircraft about barriers in their path in aviation.
  • Radar is used as a marine radar to prevent the collision from other ship.
  • Radar is used to determine the weather by meteorologists and in the weather forecast.
  • Radar is used by Geologists to determine the composition of the earth's crust.
  • Radar is used by the cops to determine vehicle speed.

Advantages

  • Radar can pierce through mediums such as clouds, fog, mist, and snow.
  • Radar signals can go through insulators.
  • Radar can provide the precise location of an object.
  • Radar can determine the velocity of a target.
  • Radar can help in calculating the distance of an object.
  • Radar can appraise the difference between stationery and moving targets.
  • Radar signals do not need a medium of transportation.
  • Radar signals can target various objects at the same time.

Disadvantages

  • Radar takes a greater amount of time to set a lock on an object.
  • Radar has quite a wider beam range over 50ft diameter.
  • Radar has a limited range of 200ft.
  • Radar cannot trace an object if it is decelerating at more than 1mph/s.
  • Radar can be intervened by numerous objects and mediums in the air.
  • Radar cannot discern or find a solution to numerous targets.
