WHAT IS It ?
• Measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects.
DID YOU KNOw...
• In the late
1930’s all of the
countries
involved in WWII
rushed to create
better radar
systems to use
in the war.
• Great Britain was one of the leading developers of radar in the years leading up to World War II.
• Britain’s built
radar stations
around the British
Isles to provide
warning of aerial
invasion. http://www.youtube.com/watch?v=0SPlmvIPv3g
WWII AND RADAR• From military point of
view two types of radar were usedfor detection and for fire control.
1• Used to create a radar
map of all objects in all directions and often as far as possible. Used for purposes such as:
DETECTION RADARS
early warning (detection of aircraft and ships)
ground controlled intercept of aircraft (done by directing fighter aircraft to detect incoming aircraft)
mapping (mapping of the ground terrain for navigation and targeting mostly by bombers)
2• Radar equivalent
of a searchlight.
Fire controls
In WWII mostly night fighters used fire control radars.

They are dedicated to the precise position of a previously detected particular target, ✓ to guide the operator to aim guns at the target and hit it without actually seeing it.

WHAT ABOUT
ADVERTISING??
DEVELOPED PROJECTS • Initially radars were
equipped with display devices like an electronics lab.
LATER…more operationally useful devices were invented, particularly the PPI (Plan Position Indicator) which is the familiar radar display which is a circular display that shows a beam which rotates with the rotating radar antenna and marks with light the positions of defected targets relative to their range.
Radar signals could also be used for navigation. (Ship or airplane)

Lets take a ride
back to the future
NOW!!...
A bigger display for your biggest
ideas.
