  2. 2. WHAT IS It ?<br />Measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects.<br />
  3. 3. DID YOU KNOw... <br />In the late 1930’s all of the countries involved in WWII rushed to create better radar systems to use in the war. <br /><ul><li>Great Britain was one of the leading developers of radar in the years leading up to World War II.
  4. 4. Britain’s built radar stations around the British Isles to provide warning of aerial invasion. </li></ul><br />
  5. 5. WWII AND RADAR<br />From military point of view two types of radar were used<br />for detection and for fire control. <br />
  6. 6. Used to create a radar map of all objects in all directions and often as far as possible. Used for purposes such as:<br />1<br />early warning (detection of aircraft and ships)<br />DETECTION RADARS<br />ground controlled intercept of aircraft (done by directing fighter aircraft to detect incoming aircraft) <br />mapping (mapping of the ground terrain for navigation and targeting mostly by bombers) <br />
  7. 7. Radar equivalent of a searchlight. <br />2<br />In WWII mostly night fighters used fire control radars. <br />★<br />Firecontrols<br />They are dedicated to the precise position of a previously detected particular target, <br />✓ to guide the operator to aim guns at the target and hit it without actually seeing it. <br />★<br />
  9. 9. DEVELOPED PROJECTS <br />Initially radars were equipped with display devices like an electronics lab. <br /><br />LATER…<br />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. <br />Radar signals could also be used for navigation. (Ship or airplane)<br />
