Micro-Doppler Estimation and Analysis of Slow Moving Objects in Forward Scattering Radar System
Remote Sensing, 2017 Micro-Doppler signature can convey information of detected targets and has been used for target recognition in many Radar systems. Nevertheless, micro-Doppler for the specific Forward Scattering Radar (FSR) system has yet to be analyzed and investigated ...

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 ...

Large Photospheric Doppler Shift in Solar Active Region 12673. I. Field-aligned Flows
The Astrophysical Journal, 2023 Delta ( δ ) sunspots sometimes host fast photospheric flows along the central magnetic polarity inversion line (PIL). Here we study the strong Doppler shift signature in the central penumbral light bridge of solar active region NOAA 12673.

Analysis of micro-Doppler signatures
IEE 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.
