Doppler radar????

Question

Can someone please give me a short, simple explanation of what doppler radar is and why it is useful. Best answer gets 10 points!

Answer 1

Doppler radar is a spherical radar device that sends out microwaves to capture 3-D images of approaching thunderstorms.

Answer 2

The Doppler radar works by measuring an energy emission.  It could be sound, light, UV, or whatever.  By continually measuring over time, it can sense the change in frequency or wavelength of the energy wave.  The changes in these two aspects allow the radar to figure out change in position and velocity.  The basic principle is known as the Doppler shift.  You can find several articles on the web, but I can't recommend one because they're all written at varying levels of academia.

Answer 3

It is the newest toy so the weather guys don't have to look out the window and know c**p.
