2. History Bats use a basic form of radar They send sound waves that reflect off of an object just as electric radar systems do
3. History The first form of radar created by humans was the telemobiloscope It was mainly used to detect ships to avoid collisions
4. 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.
5. Uses in Society 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
6. Uses in Society Airplanes use radar to avoid collisions and to coordinate landings Operators visually watch the radar outputs and relay the information to pilots
7. Uses in Society Police officers use radar to detect people who drive over the speed limit Their radar units are compact for easy portability and fast, accurate use
8. Uses in Society Ground mapping radar is often used in construction settings They drag the unit across the ground to determine if there are any objects or unstable soil where they plan on building
9. Uses in Society The military use radar to detect enemy artillery as well as their own machinery They can show where their vehicles and soldiers are in relation to enemy machines
10. Future The US Military is currently using groundbreaking radar This radar allows soldiers to see objects and people through walls
11. Future New radar in Germany is due in 2012 for ground and low altitude detection Supposed to have unmatched precision The application can potentially be branched to border surveillance
12. End 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
