decided to leave it out because it wasn't that important to me at the time. The
airplane isn't necessarily, directly connected to the SMARiTT system that is used to
monitor people. The airplane was and is a major instrument in aerial recognizance
and high altitude picture taking, but it is not necessarily used to monitor individual
people constantly.
The main reason I was going to include this in the "A Short History of
Technology" section was to show that radar was being worked on and developed
even before the airplane was perfected. This further means that the original
intent of the use of radar was not to monitor and track airplanes, but to monitor
and track things on the ground. Also, since I couldn't find the actual date radar
was invented, it didn't seem so important at the time.
As of now I think I have come relatively close to finding the actual dates the
airplane was invented and,or perfected. In my research I have found that in 1900
the Wright Brothers made their first successful manned glider flight at Kitty Hawk,
North Carolina. In 1903 they made their first successful, manned, engine powered
flight, also at Kitty Hawk. In 1905 they made their first successful, manned, engine
powered, long distance flight near Dayton, Ohio.
Radar was being worked on in the late 1800's and the early 1900's. This was
before people ever even thought that man could fly, (i.e. before airplanes). Radar
works like this; Eeewave are sent out by a transmitter, they bounce off of an
object and they come back to the receiver. The amount of time it take the
eeewaves to go out, bounce off of something and come back is measured by a
computer in time. Then the computer converts the amount of time it takes the
eeewaves to go out, bounce off of something and come back into the amount of
distance the object is away.
For example, suppose it takes one second for the eeewaves to go out,
bounce off of an object that is two hundred meters away, and come back. Then it
takes two seconds for the eeewaves to go out, bounce off of an object that is four
hundred meters away and come back. Then it takes three seconds for the
eeewaves to go out, bounce off of an object that is six hundred meters away and
come back. In this way, one second of time would equal two hundred meters.
Which means one and a half seconds would equal three hundred meters and ten
seconds would equal two thousand meters. Then the computer is mathematically
programmed and,or calibrated to let the person who is using it know how far an
object is away by measuring the amount of time it took the eeewaves to go out
and come back and then converts it into the distance.
(Note: The example above is quite simplistic and I just made up my own
numbers. Radar really does work in this way, however it is most likely measured in
millions of a second and not in seconds. Also, for this example I made it
proportional, which means one second of time equals two hundred meters,
however, since I have never actually worked with radar, I don't know if the
mathematically calculations for radar are proportional or unproportional. It is all
in the calibration.)
The frequency and,or the wavelength of the eeewaves determines the
mathematically conversion from time to distance. Sonar works in the same exact
way. Sonar is the use of sound instead of eeewaves. They just use a computer
