{"ob_id":14231,"uuid":"490b4a087f734478a243eb9fc5b31a9e","title":"Doppler radars","abstract":"A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar.
