From Modeling to Sensing of Micro-Doppler in Radio Communications

Remote Sensing, 2022
The Doppler effect in radio systems has been widely explored by the radio communication community. However, these studies have been limited to simple motion such as linear translation.

Exploring Radar Micro-Doppler Signatures for Recognition of Drone Types

Drones, 2023
In this study, we examine the use of micro-Doppler signals produced by different blades (i.e., puller and lifting blades) to aid in radar-based target recognition of small drones.

Human Activity Classification Based on Dual Micro-Motion Signatures Using Interferometric Radar

Remote Sensing, 2023
Micro-Doppler signatures obtained from the Doppler radar are generally used for human activity classification. However, if the angle between the direction of motion and radar antenna broadside is greater than 60°, the micro-Doppler signatures generated ...

Efficient Classification of Birds and Drones Considering Real Observation Scenarios Using FMCW Radar [PDF]

Journal of Electromagnetic Engineering and Science, 2021
In this study, we consider real observation scenarios and propose an efficient method to accurately distinguish drones from birds using features obtained from their micro-Doppler (MD) signatures.

Detection and Identification of Low-Slow-Small Rotor Unmanned Aerial Vehicle Using Micro-Doppler Information

IEEE Access, 2021
The capability of a radar system to detect and identify the low-slow-small rotor unmanned aerial vehicle (UAV) is intensely important for management and control in low altitude, and it can be enhanced by the characteristics of UAV, which inherently ...

Three-dimensional Micro-motion Parameters Extraction of Translational Rotating Targets Based on Vortex Electromagnetic Wave Radar

Leida xuebao, 2023
Compared with traditional Electromagnetic (EM) wave radars, vortex EM wave radars can simultaneously observe the micro-motion components projected onto the radar’s radial and perpendicular planes, providing more information for target recognition.

A RPCA-Based ISAR Imaging Method for Micromotion Targets

Sensors, 2020
Micro-Doppler generated by the micromotion of a target contaminates the inverse synthetic aperture radar (ISAR) image heavily. To acquire a clear ISAR image, removing the Micro-Doppler is an indispensable task.
