The Doppler effect, or Doppler shift, occurs when the movement of an observer relative to a source (or vice versa) causes a change in wavelength or frequency. Discovered by Austrian physicist Christian Doppler in 1842, this phenomenon is experienced in many different ways, such as when an ambu...
Doppler shift is described as the relative change of motion, speed of an object with respect to the viewer that causes the appearance of change of frequency or wavelength for a wave. It is described by a physicist Christian Doppler in 1842.[2] The change in the emitted frequency and the h...

Doppler shift uses the Doppler effect, which is the relative change in frequency of a wave when the source and the observer are in relative motion. The sound pulse generated by the ship’s motion is reflected off the ocean floor and the same is measured by sonar instruments on a ship. ...
Digital Doppler is a type of signal processing technique that uses the Doppler effect to calculate the velocity of objects...
Just days after Sputnik's launch, American scientists noticed that they could pinpoint the satellite's location based on the Doppler shift of its radio signals — a measure of how the wavelengths seemed to stretch out or contract depending on the satellite's movements. ...

the relative motion between the source of the wave and the observer. DVLs transmit a series of sound waves towards the sea bottom and then measure the frequency shift of the reflected echoes. The Doppler shift is directly proportional to the relative velocity between the vehicle and sea bottom...
Though the term redshift implies a color change, the Doppler effect applies to the entire electromagnetic spectrum. All radiation, of whichvisible lightis one type, is shifted based on the relative velocity of the source of radiation. An astronomical object that is moving away with sufficient vel...
