Doppler radar calculator

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:

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

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

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