Equivalence of the Doppler effect, relativistic Doppler effect and scattering effect

Physics Letters A, 1970
Abstract On the basis of an electromagnetic plane wave scattered by an electron, the relativistic Doppler effect is demonstrated equivalent to a two step Doppler effect. Further experimental verification for the conservation law according to the Compton-Debye theory is also urged.

The Doppler Effect

1991
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 in space, the velocities of the stars and the rotations and ...

Marine Vibrators And The Doppler Effect

Offshore Technology Conference, 1988
ABSTRACT Marine seismic data acquired with a moving vibrator suffer phase dispersion caused by Doppler shifting of the source sweep function. The dispersion, which can be as large as several hundred degrees, is a function of frequency, ship speed, sweep type, and the time dips of reflection events.
