Hint: We should know the concept of Doppler Effect and its application.
The variation gives direct and highly accurate measurements of the radial component of a target’s velocity relative to the radar.
Complete step by step answer:
Doppler Effect or Doppler shift is a phenomenon that is observed whenever the source of waves is moving with respect to an observer. An ambulance crossing you with its siren blaring is a common physical demonstration of the Doppler Effect.
A Doppler radar 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. Doppler radars are used in aviation, sounding satellites, meteorology radar guns. Hence, tracking of satellites is an application of the Doppler Effect of microwaves. Hence tracking of satellites is an application of DopplerEffect of microwave.
So, the correct answer is “Option C”.
Note:
Doppler Effect is mainly related with the relative velocities of an object by using light, sound, and other radiations. Most of the options are related to the Doppler Effect, but in question the Doppler Effect of the microwave is asked. So don’t be confused and misunderstood.
