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.

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 ...

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

Three-dimensional reconstruction of space rotating target based on narrow-band radar networks

open access: yesThe Journal of Engineering, 2019
The micro-motion of space target is an important signature for classification and recognition, which has received great attention. Based on the micro-Doppler signals from narrow-band radar networks, this study proposes a three-dimensional reconstruction ...

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.

Towards Adversarial Denoising of Radar Micro-Doppler Signatures [PDF]

open access: yes2019 International Radar Conference (RADAR), 2019
Generative Adversarial Networks (GANs) are considered the state-of-the-art in the field of image generation. They learn the joint distribution of the training data and attempt to generate new data samples in high dimensional space following the same distribution as the input.

A Novel Approach of Extracting Ship Scatterer's 3-DOF Micromotion Features Under Long Accumulation Time

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The rolling, pitching, and yawing motion of the vessel produces a micro-Doppler signature in the radar echoes. Ship scatterers’ three-degree-of-freedom (3-DOF) micromotion features contain information on the ship geometric structure and motion ...
