Ordinary Radar

Radar is used in many places in our everyday lives: in the airport, on weather channels, in space –oh wait, we don’t go to space very often– and in other locations. In space, NASA has various uses for radar; detecting asteroids, satellites, and space junk, which pose danger, are up top on its to-do list. Because of turbulence, radar is used aboard airplanes and helps the pilots avoid storms. It is also used inside the airport to track birds, since people don’t appreciate getting pooped on,  and let officials know where they are so they can be carefully let outside.

While it not only informs pilots where storms are, but radar notifies weather forecasters what is going on in the sky as well. A system called Doppler Radar uses transmitters to release radio waves, which hits the storm system and returns. The distance is calculated by the computer, which quickly reports how far away the storm is with an image. Because longer waves equal a further storm, scientists and weather forecasters can easily tell where the storm is. In the next generation of Doppler Radar, phased-array antennae will be used to transmit radar over a larger portion of the skies in a clearer vision.
