A RPCA-Based ISAR Imaging Method for Micromotion Targets
Sensors, 2020 Micro-Doppler generated by the micromotion of a target contaminates the inverse synthetic aperture radar (ISAR) image heavily. To acquire a clear ISAR image, removing the Micro-Doppler is an indispensable task.

Micro-Doppler Estimation and Analysis of Slow Moving Objects in Forward Scattering Radar System
Remote Sensing, 2017 Micro-Doppler signature can convey information of detected targets and has been used for target recognition in many Radar systems. Nevertheless, micro-Doppler for the specific Forward Scattering Radar (FSR) system has yet to be analyzed and investigated ...

Applications and Prospect of Micro-motion Theory in the Detection of Sea Surface Target
Leida xuebao, 2013 Micro-Doppler is one of the target physical characteristics. The radar signature of target with micro-motion can make fine characterization of the shape, structure and moving state of target, which reflects the nonstationary property of radar signal ...

Data-dependent micro-Doppler feature selection
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015 A vast number of features have been proposed over the years for classification of radar micro-Doppler signatures. However, the degree to which a feature may contribute in discriminating between classes depends upon a variety of operational considerations, such as antenna-target aspect angle, signal-to-noise ratio (SNR), and dwell time.

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 ...

A Doppler aliasing free micro-motion parameter estimation method in the terahertz band
EURASIP Journal on Wireless Communications and Networking, 2017 Micro-Doppler, induced by micro-motion of targets, is an important characteristic for target recognition once extracted via parameter estimation. However, micro-Doppler is usually too significant to result in aliasing in the terahertz band.

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.
