Monitoring and Analysis of Respiratory Patterns Using Microwave Doppler Radar

open access: yesIEEE Journal of Translational Engineering in Health and Medicine, 2014
Noncontact detection characteristic of Doppler radar provides an unobtrusive means of respiration detection and monitoring. This avoids additional preparations, such as physical sensor attachment or special clothing, which can be useful for certain ...

On the Analysis of Single-Doppler Radar Data [PDF]

open access: yesJournal of Applied Meteorology, 1979
Abstract The procedures currently employed to retrieve vector wind information from single-Doppler radar observations are reviewed briefly. In particular, those procedures implying a linearity hypothesis for the wind field are shown to be particular cases of a method termed VVP (Volume Velocity Processing).

Dop‐NET: a micro‐Doppler radar data challenge

open access: yesElectronics Letters, 2020
Radar sensors have a new growing application area of dynamic hand gesture recognition. Traditionally radar systems are considered to be very large, complex and focused on detecting targets at long ranges.

Doppler spectra from DWD's operational C-band radar birdbath scan: sampling strategy, spectral postprocessing, and multimodal analysis for the retrieval of precipitation processes [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
This study explores the potential of using Doppler (power) spectra from vertically pointing C-band radar birdbath scans to investigate precipitating clouds above the radar. First, the new birdbath scan strategy for the network of dual-polarization C-band

FDA-MIMO Radar Moving Target Detection Based on Doppler Spread Compensation

open access: yesLeida xuebao, 2022
When Frequency Diverse Array and Multiple-Input Multiple-Output (FDA-MIMO) radar detects moving targets, the frequency offset between transmitting arrays is coupled with the target velocity, resulting in severe Doppler spread in the slow time dimension ...

Radarize: Enhancing Radar SLAM with Generalizable Doppler-Based Odometry [PDF]

open access: yes, 2023
Millimeter-wave (mmWave) radar is increasingly being considered as an alternative to optical sensors for robotic primitives like simultaneous localization and mapping (SLAM). While mmWave radar overcomes some limitations of optical sensors, such as occlusions, poor lighting conditions, and privacy concerns, it also faces unique challenges, such as ...
