Classification of small UAVs and birds by micro-Doppler signatures [PDF]

open access: yesInternational Journal of Microwave and Wireless Technologies, 2014
The popularity of small unmanned aerial vehicles (UAVs) is increasing. Therefore, the importance of security systems able to detect and classify them is increasing as well. In this paper, we propose a new approach for UAVs classification using continuous wave radar or high pulse repetition frequency (PRF) pulse radars.

Micro-Doppler Ambiguity Resolution Based on Short-Time Compressed Sensing

open access: yesJournal of Electrical and Computer Engineering, 2015
When using a long range radar (LRR) to track a target with micromotion, the micro-Doppler embodied in the radar echoes may suffer from ambiguity problem.

Efficient Protocol to Use FMCW Radar and CNN to Distinguish Micro-Doppler Signatures of Multiple Drones and Birds

open access: yesIEEE Access, 2022
Classification of multiple drones and birds by comparing micro-Doppler (MD) signatures is a very difficult task because the MD signatures of multiple birds can contaminate the MD signature of drones, and because a single drone can yield a very similar MD

UAV Recognition Based on Micro-Doppler Dynamic Attribute-Guided Augmentation Algorithm

open access: yesRemote Sensing, 2021
A micro-Doppler signature (m-DS) based on the rotation of drone blades is an effective way to detect and identify small drones. Deep-learning-based recognition algorithms can achieve higher recognition performance, but they needs a large amount of sample

Micro-Doppler feature extraction under passive radar based on orthogonal frequency division multiplexing communication signal

open access: yesThe Journal of Engineering, 2019
Micro-Doppler (m-D) effect is a unique signature of radar targets with micro-motion, which provides a new technique for target recognition. Passive radar based on communication signal has a great significance in detection and recognition for micro-motion

Review of micro‐Doppler signatures

open access: yesIET Radar, Sonar & Navigation, 2015
Micro‐Doppler signals refer to Doppler scattering returns produced by the motions of the target other than gross translation. The small micro‐motions of a subject, and even just parts of a subject, can be observed through the micro‐Doppler signature it creates in response to an active emitter such as a radar, laser, and even acoustic emitters.

Linear Discriminant Analysis-Based Motion Classification Using Distributed Micro-Doppler Radars with Limited Backhaul

open access: yesSensors, 2021
In this paper, we propose a cooperative linear discriminant analysis (LDA)-based motion classification algorithm for distributed micro-Doppler (MD) radars which are connected to a data fusion center through the limited backhaul.

Causal Localization Network for Radar Human Localization With Micro-Doppler Signature

open access: yesIEEE Access
The Micro-Doppler (MD) signature includes unique characteristics from different-sized body parts such as arms, legs, and torso. Existing radar identification systems have attempted to classify human identification using these characteristics in MD ...

Micro-Doppler signature for drone detection using FSR: a theoretical and experimental validation

open access: yesThe Journal of Engineering, 2019
Drone inexpensive and operational flexibility contributed to its exponential increase by civil users, apart from military applications. This resulted in posing threats due to drone misuses, such as smuggling, unlawful imaging and other significant ...
