Recently, an L-statistics based method for the micro-Doppler effects removal has been proposed by the authors. Order statistics is performed on the spectrogram, while the rigid body signal.
Interests: microwave sensors; radar imaging; radar target detection; through-barrier sensing Special Issue Information Through-wall radars are attracting notable interest for the identification of targets in complex and closed or inaccessible building environments, thanks to the capability of electromagnetic signals to penetrate opaque media in frequencies ranging from some hundreds of.
In radar imaging, it is well known that relative motion or deformations of parts of illuminated objects induce additional features in the Doppler frequency spectrum. These features are called micro-Doppler effect and appear as sidebands around the central Doppler frequency. They can provide valuable information about the structure of the moving parts and may be used for identification purposes.
Micro-Doppler Effect in Radar: Phenomenon, Model, and Simulation Study VICTOR C. CHEN Naval Research Laboratory FAYIN LI SHEN-SHYANG HO HARRY WECHSLER, Fellow, IEEE George Mason University When, in addition to the constant Doppler frequency shift induced by the bulk motion of a radar target, the target or any.
Micro-Doppler gives rise to many detailed radar image features in addition to those associated with bulk target motion. Targets of different classes (for example, humans, animals, and vehicles) produce micro-Doppler images that are often distinguishable even by nonexpert observers.
Since the notion of micro-Doppler effect was originally introduced in coherent laser systems, , lots of researches based on micro-Doppler effect have been presented, ,, , which demonstrate micro-Doppler frequencies accord with target micro-motion and the corresponding micro-Doppler features can be utilized to depict the micro-motion structures of the targets. The dynamic properties of the.
