The Doppler effect, named for Christian Doppler (ca. 1842), has tremendous importance for science and technology. Thanks to it, air traffic controllers can distinguish among objects moving in the line of sight; on the ground, speeding cars can be identified before serious accidents occur; and ...

The Doppler effect is observed whenever the source of waves is moving relative to an observer. 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 to
This paper first shows that the Doppler frequency shift affects the frequencies of the RF carrier, subcarriers, envelope, and symbol timing by the same percentage in an Orthogonal Frequency Division Multiplexing (OFDM) signal or any other modulated signals. Then the SNR degradation of an OFDM syst...
How does the Doppler Effect work? If the source of radiation, say astar, is moving toward an astronomer on Earth (for example), then the wavelength of its radiation will appear shorter (higher frequency, and therefore higher energy). On the other hand, if the object is moving away from ...
摘要: The Doppler effect is today applied in themes ranging from aerial navigation to the expanding universe. This article describes the origin of the principle, which was first put forward with astronomical application in view, its history and present employment....
