Doppler radar is a radar that uses the Doppler effect for
positioning, speed measurement, and ranging.
The so-called Doppler effect is that when the vibration
source such as sound, light and radio waves and
the observer move relative to each other at a relative
velocity V, the vibration frequency received by
the observer is different from the frequency emitted by
the vibration source. Because this phenomenon
was first discovered by the Austrian scientist Doppler,
it is called the Doppler effect. The frequency
change formed by the Doppler effect is called the Doppler
shift, which is proportional to the relative
velocity V and inversely proportional to the frequency of
the vibration.

Formula:

\(Frequency shift (Fr) = Ft × ( (1+(v/c)) / (1-(v/c)) )\)

\(Doppler frequency (Fd) = Fr - Ft\)

\(Ft = original frequency, c = speed of light \)
