Electromagnetic Doppler effect in non-reciprocal medium
AIP Advances, 2023 Reflected light from a moving object, such as a mirror, is frequency-shifted via the Doppler effect. This well-known phenomenon is used to determine the speed and direction of an object due to the red or blue shifting of the received electromagnetic ...

Folded Chirp-Rate Shift Keying Modulation for LEO Satellite IoT
IEEE Access, 2019 In the low earth orbit (LEO) satellite Internet of Things (IoT), the IoT devices can be distributed in remote areas (e.g., desert, ocean, and forest) for some special applications, where they are unable to have direct terrestrial network accesses and can

Echo Delay and Overlap with Emitted Orientation Sounds and Doppler-shift Compensation in the Bat, Rhinolophus ferrumequinum [PDF]
, 1977 The compensation of Doppler-shifts by the bat, Rhinolophusferrumequinum, functions only when certain temporal relations between the echo and the emitted orientation sound are given. Three echo configurations were used: a) Original orientation sounds were

Doppler shift simulation of scattered HF signals during the Tromsø HF pumping experiment on 16 February 1996 [PDF]
Annales Geophysicae, 2002 Comparisons between bistatic scatter measurements and simulation results during the Tromsø HF pumping experiment on 16 February 1996 are made. Doppler measurements of an HF diagnostic signal scattered from the field-aligned irregularities (FAIs) in

Single camera three component planar velocity measurements using two-frequency planar Doppler velocimetry (2ν-PDV) (2012) [PDF]
, 2006 Two-frequency planar Doppler velocimetry (2ν-PDV) is used in conjunction with imaging fibre bundles to make time-averaged three component velocity measurements using a single CCD camera and iodine cell. In this scheme the flow is sequentially illuminated

New bounds of wide‐gap frequency‐hopping sequences with frequency shift
Electronics Letters, 2022 With the rapid development of radar, the phenomenon of Doppler frequency shift is not rare. Frequency shift needs to be considered in order to accurately calculate the mutual interference between signals. Meanwhile, to reduce interference to the received
