Experimental measurements of radar signatures of large wind turbine
The Journal of Engineering, 2019 This study presents preliminary results on the signature of a large offshore wind turbine collected using an active S-band radar. The intensity fluctuations of this clutter signal in the range and Doppler domain are characterised, looking at their ...

High-latitude HF Doppler observations of ULF waves: 2. Waves with small spatial scale sizes [PDF]
Annales Geophysicae, 1999 The DOPE (Doppler Pulsation Experiment) HF Doppler sounder located near Tromsø, Norway (geographic: 69.6°N 19.2°E; L = 6.3) is deployed to observe signatures, in the high-latitude ionosphere, of magnetospheric ULF waves.

IEEE 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

Hand Gesture Recognition based on Radar Micro-Doppler Signature Envelopes [PDF]
International Radar Conference, 2018 We introduce a simple but effective technique in automatic hand gesture recognition using radar. The proposed technique classifies hand gestures based on the envelopes of their micro-Doppler (MD) signatures. These envelopes capture the distinctions among

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
