The Doppler Effect

Elementary Approach to Special Relativity, 2020
In every advanced course on physics the Doppler, effect is usually the standard example for demonstrating the fundamental physical differences between the propagation of elastic waves through a mechanical medium and the propagation of electromagnetic waves through our physical space.

Precession Parameter Estimation of Warhead With Fins Based on Micro-Doppler Effect and Radar Network

IEEE Transactions on Aerospace and Electronic Systems, 2023
Precession is a typical micromotion of a ballistic missile warhead in the middle of the trajectory. The modulation of the narrow-band radar echo by the precession warhead is mainly reflected in the micro-Doppler effect, which is manifested as the Doppler

Rethinking Doppler Effect for Accurate Velocity Estimation With Commodity WiFi Devices

IEEE Journal on Selected Areas in Communications, 2022
Enabling pervasive WiFi devices with non-contact sensing capability is an important topic in the field of integrated sensing and communication. Doppler effect has been widely exploited to estimate targets’ velocity from wireless signals.

Analysis of misaligned optical rotational Doppler effect by modal decomposition.

Optics Express, 2021
The optical rotational Doppler effect (RDE) is closely related to the unique orbital angular momentum (OAM) carried by optical vortex, whose topological charge means the mode of OAM.

Remote detection of a rotator based on rotational Doppler effect

Applied Physics Express, 2020
Based on the rotational Doppler effect arising from optical orbital angular momentum , we proposed the detection system of a rotator over a distance, by probing the object with a Laguerre–Gauss beam and a Kepler telescope.

Doppler effect in the time-domain beamforming for rotating sound source identification.

Journal of the Acoustical Society of America, 2020
Identifications of rotating sound sources are of interest in many industrial applications. The most famous beamforming to identify rotating sound source is the time-domain ROSI beamforming proposed by Sijtsma et al. (AIAA 2001-2167, 2001).

Influence of lateral misalignment on the optical rotational Doppler effect.

Applied Optics, 2019
The discovery of the optical rotational Doppler effect associated with orbital angular momentum of light paves a new way to detect the rotational speed of spinning objects.
