What is Doppler shift in satellite communication?
The Doppler shift is observed when a source of waves is moving in relation to an observer or vice versa. This movement produces a change in frequency in relation to observer. Without loss of generality, we will focus on the case where the source is approaching the destination.
What is the effect of the Doppler shift?
The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the source is receding.
What is an example of the Doppler shift?
The drop in pitch of ambulance sirens as they pass by and the shift in red light are common examples of the Doppler Effect. Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect.
