Sentence examples for using the doppler shift from inspiring English sources
As one measures the relative speeds of galaxies using the Doppler shift of characteristic radiation emissions, one finds that all galaxies are moving away from one another.
In 1912 Vesto Slipher began at the Lowell Observatory in Arizona an extensive program to measure the velocities of nebulas, using the Doppler shift of their spectral lines.
Frank McClure, then chairman of the Applied Physics Laboratory (APL) at Johns Hopkins University in Baltimore, saw the navigational possibilities of using the Doppler shift from a satellite to locate a receiver on earth.The following year, with money from the Pentagon, scientists at APL began to develop a satellite navigation system called Transit.
The radars measure the position using ranging results and the velocity using the Doppler shift [29].

VISAR uses the Doppler shift associated with reflecting light from an accelerating surface.
Like a GPS-equipped radiosonde, the unit uses the Doppler shift in the signals from four satellites to triangulate and measure velocity.
This method uses the Doppler shift (i.e. the frequency change that light undergoes when reflected by objects in motion, such as RBCs) and has been proposed to be a valid method for the monitoring of microcirculatory function in small, discrete tissue areas (for a review see Smits et al, 1986).
While the Argos collars determined animal locations using the Doppler-shift method through the Argos satellite system, the GPS-Argos collars used the Argos system only for data transfer of GPS locations.
