Numerical and Experimental Studies on the Micro-Doppler Signatures of Freely Flying Insects at W-Band

open access: yesRemote Sensing, 2022
Remote sensing techniques in the microwave frequency range have been successfully used in the context of bird, bat and insect measurements. This article breaks new ground in the analysis of freely flying insects by using a continuous-wave (CW) radar ...

A Trajectory-Driven 3D Channel Model for Human Activity Recognition

open access: yesIEEE Access, 2021
This paper concerns the design, analysis, and simulation of a 3D non-stationary channel model fed with inertial measurement unit (IMU) data. The work in this paper provides a framework for simulating the micro-Doppler signatures of indoor channels for ...

Micro-Doppler Estimation and Analysis of Slow Moving Objects in Forward Scattering Radar System

open access: yesRemote 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 ...

Obfuscation of Human Micro-Doppler Signatures in Passive Wireless RADAR

open access: yesIEEE Access, 2023
When wireless communication signals impinge on a moving human they are affected by micro-Doppler. A passive receiver of the resulting signals can calculate the spectrogram that produces different signatures depending on the human activity.

Coupled micro-Doppler signatures of closely located targets [PDF]

open access: yesPhysical Review B, 2019
The classical Doppler shift originates from the movement of a target's center of mass, but it does not hold information about the internal dynamics of the scattering object. In contrast, micro-Doppler signatures contain data about the micro-motions that arise from internal degrees of freedom within the target (such as rotation and vibration), which can

Applications and Prospect of Micro-motion Theory in the Detection of Sea Surface Target

open access: yesLeida 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 ...

Classification of unarmed/armed personnel using the NetRAD multistatic radar for micro-Doppler and singular value decomposition features [PDF]

open access: yes, 2015
In this letter, we present the use of experimental human micro-Doppler signature data gathered by a multistatic radar system to discriminate between unarmed and potentially armed personnel walking along different trajectories.

Pedestrian and Animal Recognition Using Doppler Radar Signature and Deep Learning

open access: yesSensors, 2022
Pedestrian occurrences in images and videos must be accurately recognized in a number of applications that may improve the quality of human life. Radar can be used to identify pedestrians.

A novel algorithm for radar classification based on Doppler characteristics exploiting orthogonal pseudo-Zernike polynomials [PDF]

open access: yes, 2015
Phase modulation induced by target micro-motions introduces side-bands in the radar spectral signature returns. Time-frequency distributions facilitate the representation of such modulations in a micro-Doppler signature that is useful in the ...

Analysis of micro-Doppler signatures

open access: yesIEE Proceedings - Radar, Sonar and Navigation, 2003
Mechanical vibration or rotation of a target or structures on the target may induce additional frequency modulations on the returned radar signal which generate sidebands about the target's Doppler frequency, called the micro-Doppler effect. Micro-Doppler signatures enable some properties of the target to be determined.
