Classification of human micro-Doppler in a radar network

2013 IEEE Radar Conference (RadarCon13), 2013
The unique, bi-pedal motion of humans has been shown to generate a characteristic micro-Doppler signature in the time-frequency domain that can be used to discriminate humans from not just other targets, but also between different activities, such as walking and running.

Multistatic radar micro-Doppler

2020
This chapter reviews how multistatic radar sensor networks can be utilised to sense a series of different moving targets to extract their micro-Doppler (μD) signatures and use these for classification purposes. The field of radar has advanced significantly since its inception in the early twentieth century.

Experimental Observations of Micro-Doppler Signatures With Passive Radar

IEEE Transactions on Aerospace and Electronic Systems, 2019
Passive radar's ability to observe micro-Doppler phenomena from helicopters, fixed-wing propeller aircraft, and jet engine modulation is examined. Experimental results from a digital television based passive radar demonstrate its potential to observe characteristic signatures of multiple types of air targets and estimate helicopters’ primary rotor ...

Micro-doppler radar for human breathing and heartbeat detection

2015 Computational Electromagnetics International Workshop (CEM), 2015
Detection of live-human presence under the debris is a critical problem especially after natural disasters such as earthquakes and landslides. If a radar system can detect breathing and heartbeats, it would be invaluable and preferable to existing acoustic or ultrasound based systems.

Acoustic micro-Doppler radar for human gait imaging

The Journal of the Acoustical Society of America, 2007
A portable acoustic micro-Doppler radar system for the acquisition of human gait signatures in indoor and outdoor environments is reported. Signals from an accelerometer attached to the leg support the identification of the components in the measured micro-Doppler signature.

Micro-Doppler analysis and application of radar targets

2008 International Conference on Information and Automation, 2008
Radar target micro-Doppler signatures reflect the electromagnetic characteristics, geometry structures and motion signatures of the target, which has been shown to be promising signatures for application. In this paper, we review the present research status and some key techniques in this field, including the analysis of micro-Doppler signatures ...

Visualizing and displaying radar micro-doppler data

SPIE Proceedings, 2011
A time-integrated range-Doppler map shows the micro-Doppler characteristics of targets in radar images that enable an operator to classify different target types and to classify different activities being done by the targets. A time-integrated range-Doppler map is a compilation of range-Doppler maps over time that results in a spectrogram-like ...

Wideband radar micro-doppler applications

SPIE Proceedings, 2013
Wideband radar provides a significant improvement over traditional narrowband radars for micro-Doppler analysis because the high bandwidth can be used to separate many of the signals in range, allowing a simpler decomposition of the micro-Doppler signals. Recent wideband radar work has focused on micro-Doppler, but there is a point where the narrowband

Radar Micro-Doppler Signature Analysis with HHT

IEEE Transactions on Aerospace and Electronic Systems, 2010
Radar micro-Doppler signature analysis of vibrating targets with the joint time-frequency methods can provide useful information for target detection, classification, and recognition. We employ a well-known method for nonlinear and nonstationary signals, Hilbert-Huang transform (HHT) as a new approach in micro-Doppler analysis.

Micro-Doppler Signature Extraction with Multibeam Radar

2019 International Radar Conference (RADAR), 2019
Orthogonal and quasi-orthogonal waveforms are used in a multibeam radar (MBR) to isolate different channels and reduce cross-channel interference. Each channel provides an independent radar beam that performs a specific functionality without interfering with adjacent channels.
