2.4.8Doppler effect (De) TheDoppler effectcan be described as the frequency shifts noticed in transmitted waves when the source and destination are inrelative motion(Chang et al., 2023). The challenge in the UAV-based DC process is that theDoppler effectcauses significant inter-carrier interferen...
DOPPLER effectASTROPHYSICSRELATIVE motionVECTOR fieldsGALAXY formationWe present a novel approach for rendering volumetric data including the Doppler effect of light. Similar to the acoustic Doppler effect, which is caused by relative motion between a sound emitter and an observer, light waves also ...
The Doppler effect refers to the change in frequency of a wave source as a consequence of the relative motion between the source and an observer. Veselago theoretically predicted that materials with negative refractions can induce inverse Doppler effects. With the development of metamaterials, inverse...
and the range of gray levels used is from -63 to +63. The grayscale value to be displayed is bounded by the values of -63 to +63. The spectral waveform is further adjusted so as to simulate the effect of changes in spectral gain, by decreasing the minimum depicted velocity, and sligh...
The Doppler-effect enables US to be used to detect motion. US Doppler systems display the Doppler frequency shift produced by moving objects in an US beam (Fig. 5.22). Commonly, it is used to measure the velocity of the blood flow but also in detecting the velocity of structure movements,...

This chapter discusses the data processing technique of PD radar. It presents ...
Our ears detect an interaural time difference because of their different positions (and therefore infer the lateral position of a sound source) and also sense the distance of the approaching train from an increase in frequency caused by the Doppler effect. Jensen (Jensen, 2001; Udesen & Jensen,...
