eriradar, mis kasutab Doppleri efekti kauguses olevate objektide kiiruse kohta mõõteandmete saamiseks tagasipeegeldunud mikrolainesignaali sageduse muutuse põhjal
specialized radar that uses the Doppler effect to produce velocity data about objects at a distance, and 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
