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

Continual Learning of Micro-Doppler Signature-Based Human Activity Classification

IEEE Geoscience and Remote Sensing Letters, 2021
Human activity classification based on micro-Doppler signatures measured by radar recently has been successfully applied in diverse applications due to the improvement of machine learning methods, e.g., deep convolutional neural networks (DCNNs). Despite

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

Doppler Shift Signature for a MCSs Selection in a VANET

The Smart Computing Review, 2014
The emergence of Intelligent Transportation Systems has given new hope and an unprecedented number of promising benefits to the transportation industry. However, these benefits are accompanied with inherent challenges due to the higher mobility of the vehicular nodes. One of the major problems faced is the induced Doppler shift in the carrier frequency

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 ...

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 ...

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.

Micro-Doppler radar signatures of human activity

SPIE Proceedings, 2010
We will present the continued development of a millimeter-wave/sub-THz radar system used to capture and assess micro-Doppler signatures of humans. This system is being developed to remotely monitor respiration and heartbeat rates at standoff distances of up to 100 meters.

FMCW Radar Range Profile and Micro-Doppler Signature Fusion for Improved Traffic Signaling Motion Classification

International Radar Conference
Human activity recognition plays a crucial role in Advanced Driver-Assisted Systems (ADAS). A significant challenge in achieving automotive autonomy lies in the difficulty faced by self-driving cars in navigating roads without operational traffic lights.
