A Multi-Rotor Drone Micro-Motion Parameter Estimation Method Based on CVMD and SVD
Remote Sensing, 2022 It is of great significance to detect drones in airspace due to the substantial increase and regrettable misuse in the consumer market. In this paper, we establish a micro-motion theoretical model of a drone and analyze the micro-Doppler signature of ...

Developments in target micro-doppler signatures analysis: radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Obfuscation of Human Micro-Doppler Signatures in Passive Wireless RADAR
IEEE 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
Leida 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]
Physical 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
