Radar: A Silent Eye In The Sky - Research Paper

Radar: A Silent Eye In The Sky

Today's society relies heavily on an invention taken for granted: radar.
Just about everybody uses radar, whether they realize it or not. Tens of
thousands of lives rely on the precision and speed of radar to guide their plane
through the skies unscathed. Others just use it when they turn on the morning
news to check the weather forecast.

While radar seems to be an important part of our everyday lives, it has

(S/2) X 1100 = D (Half of the total time times 1100 feet
per second equals the distance from the origin to the reflection point)

Of course, radar is a much more complicated system than just somebody
shouting and listening for the echo. In fact, modern radar listens not only for
an echo, but where the echo comes from, what direction the object is moving, its
speed, and its distance. There are two types of modern radar: continuous wave
radar, and pulse radar.

Pulse radar works like an echo. The transmitter sends out short bursts
of radio waves. It then shuts off, and the receiver listens for the echoes.
Echoes from pulse radar can tell the distance and direction of the object
creating the echo. This is the most common form of radar, and it is the one
that is used ...
