Gait classification based on micro-Doppler features [PDF]
2016 CIE International Conference on Radar (RADAR), 2016 This paper focuses on the classification of human gaits based on micro-Doppler signatures. The micro-Doppler signatures can represent detailed information about the human gaits, which helps in judging the threat of a personnel target. The proposed method consists of three major steps.

Review of micro‐Doppler signatures
IET Radar, Sonar and Navigation, 2015 Micro‐Doppler signals refer to Doppler scattering returns produced by the motions of the target other than gross translation. The small micro‐motions of a subject, and even just parts of a subject, can be observed through the micro‐Doppler signature it creates in response to an active emitter such as a radar, laser, and even acoustic emitters.

Research on micro-Doppler feature of spatial target [PDF]
EURASIP Journal on Wireless Communications and Networking, 2017 The micro-Doppler (m-D) effect which is also called micro-motion effect is a kind of physical phenomenon, which is often produced in ISAR imaging of space targets. When the space target has a micro-Doppler effect, it will produce frequency modulation for

Knowledge Exploitation for Human Micro-Doppler Classification
IEEE Geoscience and Remote Sensing Letters, 2015 Micro-Doppler radar signatures have great potential for classifying pedestrians and animals, as well as their motion pattern, in a variety of surveillance applications. Due to the many degrees of freedom involved, real data need to be complemented with accurate simulated radar data to be able to successfully design and test radar signal processing ...
