How does a doppler radar work?



  1. 0 Votes

    A doppler radar uses the doppler effect to find information about objects at a distance. The doppler effect is essentially the change in frequency for an observer relative to the producer of the wave. So, as sirens approach somebody, the frequency is higher, and then lower as the sirens pass, resulting in that doppler effect sound. A doppler radar uses the variations in frequency to measure data, such as with a police speed gun.
