Since the Doppler frequency shift is proportional to radial velocity, a radar system that measures such a shift in frequency can provide the radial velocity of a target.

Britannica

The Doppler effect is a shift in frequency of the sound heard by an observer who moves relative to the sound source.

SEP

where (d_{n}^{(0)}) is either QAM/PSK symbol (also after DFT precoding, if considered) transmitted at subcarrier indexed n, and the shift (n+frac {1}{2}) is due to the application of the legacy SC-FDMA scheme, where such a shift in frequency is introduced.

EURASIP Journal on Wireless Communications and Networking

Light which is backscattered from moving erythrocytes undergoes a shift in frequency that is proportional to their velocity in accordance to the Doppler principle [44], hence making it possible to obtain reproducible measurements of blood flow at a single spot defined by the incident and Doppler-shifted reflected light [45].

Intensive Care Medicine Experimental

In contrast, rSgsE showed a different behavior as there was an increase in dissipation to a maximum of approximately 0.8 × 10−6 up to a shift in frequency of −20 Hz and subsequently the dissipation dropped down with increasing mass (decreasing frequency; Fig. 4B) to a constant value from a shift in frequency of approximately −40 Hz (Fig. 5).

Acta Biomaterialia

The 780 nm wave length light generated by the laser is directed to the skin using an optic-fibre probe and reflects from the moving blood cells undergoing a shift in frequency (Doppler effect).

The peaks of the metabolites are identified by their frequency and expressed as a shift in the frequency relative to a standard, typically water, which is highly concentrated in human tissues.

Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy

For example, in paediatric ICU patients with organ dysfunction, HRV evaluated using a frequency distribution (plotting frequency of occurrence of differences from the mean) revealed a reduction in HRV and a shift in the frequency distribution to the left with increasing organ failure; these changes improved in surviving patients and were refractory in nonsurvivors [ 33].

Critical Care

Through measurement of a shift in signal frequency influenced by the ship's motion the vessel's position is auto matically calculated.

The New York Times

The non-Doppler radars provide estimates of precipitation intensity, while Doppler radars can also provide estimates of wind speed and direction by detecting a shift in the frequency of an echo produced by a moving target.

Britannica

A shift in the frequency of light received from a moving source had been proposed in 1842 by the Austrian physicist Christian Doppler, who (wrongly) thought that in this way he could explain the colours of binary stars.
