This presentation is about radar and is presented by 6 students to their lecturer. It includes an introduction, history of radar including its development from experiments in the late 19th century to use in World War II. It also outlines the different types of radar, how radar works, and its various applications such as in weather forecasting, air traffic control, police speed detection, and military uses. The presentation concludes by discussing advances in radar technology and its increasing role in the future.

6.  “RADAR” Acronym for Radio
Detection And Ranging.
 First Successfully demonstrated
in 1936.
 It uses electromagnetic waves.
 It enjoys wide range of application.

7.  The history of RADAR starts with experiments by Heinrich Hertz
in the late 19th century.
The first form of RADAR created by humans was the
telemobilescope.
 It was mainly used to detect ships to avoid collisions
Telemobilescope ( The first form of RADAR )

8. HISTORY
 RADAR was kept fairly secret during
world war II.
Following the war, it was published
that the United States used RADAR
to measure the distance to the
moon.
 It was later discovered that Hungary
had done this two years earlier than
the U.S.

10. Bats use a basic form of RADAR.
 They send sound waves that
reflect of an object just as
electric RADAR systems do.

13.  A common use of RADAR is
in forecasting the daily
weather.
 For example, they use RADAR
to reflect off of moisture in
the air to predict
precipitation.

14.  Airplanes use RADAR to avoid
collisions and to co-ordinate landings.
Operators visually watch the RADAR
outputs and relay the information
to pilots.

15.  Police officers use RADAR to detect people who drive over the
speed limit.
The military use RADAR to detect enemy artillery as well as their
own machinery.
 Ground mapping RADAR is often used in construction settings.

16.  RADAR is used to find velocity, range and position of the object.
 LIDER is Advanced type of RADAR which uses visible light from
LASER
 Technology will continue to grow, and RADAR will advance with
it.
 Growth of RADAR technologies will be accompanied by a wider
variety of applications.
 RADAR in the future will most likely be as common as cell phone
applications are today.
