What is Radar?
RADAR (Radio Detection And Ranging) is a way to detect and study far off targets by transmitting a radio pulse in the direction of the target and observing the reflection of the wave.
It s basically radio echo
The Range
The 2 is because the measured time is for a round trip to and from the target. To determine the range, you only want the time to the object, so you take half!
Types and Uses of Radar
Search radars scan a large area with pulses of short radio waves
Targeting radars use the same principle but scan a smaller area more often
Navigational radars are like search radar, but use short waves that reflect off hard surfaces. They are used on commercial ships and long-distance commercial aircraft
Incoherent Scatter Radar- A Radar Application
Used to study the Earth's ionosphere and its interactions with the upper atmosphere, the magnetosphere, and the solar wind
