Analysis of Micro-Doppler Signatures of Small UAVs Based on Doppler Spectrum

IEEE Transactions on Aerospace and Electronic Systems, 2021
Most of the investigations on the micro-Doppler (MD) effect caused by a small unmanned aerial vehicle (UAV) have been conducted using joint time–frequency (JTF) images rather than the Doppler spectrum. On the other hand, several researchers utilized the Doppler spectrum instead of JTF images to observe the MD signature of a small UAV, and found the ...

De-Dopplerization of acoustic signatures

Journal of the Acoustical Society of America, 2016
Shifting energy within and between adjacent fractional octave bands removes Doppler shifting in overflight measurements of acoustic signatures without complex resampling techniques and stationary requirements. Analyzing acoustic measurements with Fourier transforms to obtain spectral information requires complex resampling to overcome stationary signal

Micro-Doppler Signature Classification

2006 CIE International Conference on Radar, 2006
The micro-Doppler signature of a target is a time varying frequency modulation imparted on the radar echo signal by moving components of the target. Battlefield radar output the radar's baseband signal as audio and soldiers listening on headphones are able to identify the target from its micro-Doppler signature.

Doppler Signatures of Hard Targets

Topical Meeting on Coherent Laser Radar Technology and Applications, 1987
Monostatic coherent doppler signal-to-noise (S/N) ratio measurements were made with a 15 watt, continuous wave, homodyne 10.6 micrometer ladar. The path from the ladar to the target was 30m horizontal with a single fold of the beam to maximize path length. The beam was focused at the target through the 25cm aperture Schwartzchild telescope. Attenuation

UAV Micro-Doppler Signature Analysis

2020 IEEE Radar Conference (RadarConf20), 2020
The radar phenomenology of UAVs interacts with the micro-Doppler signal processing in interesting and useful ways. This paper adjusts the micro-Doppler processing to establish more consistent UAV micro-Doppler signatures and improve the separability of relevant features. The outlined approach is developed in the context of UAV rotor analysis.

Exploitation of radar Doppler signatures for gait analysis

2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012
The purpose of this study was to measure radar signal returns to explore if differences in gait patterns of individuals under certain conditions could be exploited from radar Doppler signatures. Abnormalities in gait associated with some forms of concussion as well as other neurological diseases that manifest in the walking gait could be a future ...

Radar-Based Monitoring of the Worker Activities by Exploiting Range-Doppler and Micro-Doppler Signatures

2021 IEEE International Workshop on Metrology for Industry 4.0 & IoT (MetroInd4.0&IoT), 2021
Long-term sedentary behavior severely increases the risk of developing diseases and syndromes. Cardiovascular and skeletal muscle issues, higher blood pressure and cholesterol levels are among this long list of consequences. Although a great effort was devoted to fight sedentary behaviors by means of public health strategies and the employment of ...

Template based micro-Doppler signature classification

IET Seminar on High Resolution Imaging and Target Classification, 2006
The micro-Doppler signature of a target is a time varying frequency modulation imparted on the radar echo signal by moving components of the target. Battlefield radar output the baseband signal as audio and soldiers listening on headphones are able to identify the target from its micro-Doppler signature.
