From Modeling to Sensing of Micro-Doppler in Radio Communications
Remote Sensing, 2022 The Doppler effect in radio systems has been widely explored by the radio communication community. However, these studies have been limited to simple motion such as linear translation.

Micro-Doppler Photoacoustic Effect and Sensing by Ultrasound Radar [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2016 In recent years, photoacoustics have been studied for both anatomical and functional biomedical imaging. However, the physical interaction between photoacoustic-generated endogenous waves and an exogenously applied ultrasound wave is a largely unexplored area.

Micro-Doppler Effect of Extended Streamlined Targets Based on Sliding Scattering Centre Model [PDF]
Radioengineering, 2016 The scattering center of extended streamlined targets can slide when the direction of radiation is changed. The sliding scattering center has influence on the micro-Doppler effect of micro-motion of the extended streamlined target.

Chipless RFID Based on Micro-Doppler Effect
IEEE Transactions on Microwave Theory and Techniques, 2022 This paper demonstrates how motion effect can be exploited to read moving chipless RFID tags at larger distances compared to what has been reached without benifitly taking into account the movement. According to the Doppler effect, due to the time-variant behaviour of moving chipless tags, the tag back-scattered field contains frequency components ...

Decision Fusion and Micro‐Doppler Effects in Moving Sonar Target Recognition
International Journal of Intelligent Systems, 2023 This paper proposes a method for underwater target recognition based on micro‐Doppler effects (called STR_MD) using a majority voting ensemble classifier weighted with particle swarm optimization (PSO) (called MV‐PSO). The micro‐Doppler effect refers to amplitude/phase modulation of the received signal by rotating parts of a target such as propellers ...

Research Advances on the Rotational Doppler Effect of Vortex Electromagnetic Waves
Leida xuebao, 2021 Traditional radars can detect moving targets using the Doppler effect. However, traditional radars have shadow areas in detecting the angular motion of the rotating targets.

Developments in target micro-doppler signatures analysis: radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.
