An L-statistics based method for micro-Doppler effects removal is proposed in this paper. The L-statistics approach is performed on the spectrogram, while the rigid body signal synthesis is done in the complex time-frequency domain.
The micro-Doppler (m-D) effect appears in the inverse synthetic aperture radar (ISAR) imaging when a target has one or more fast moving parts -.
Genetic algorithm for rigid body reconstruction after micro-doppler removal in the radar imaging analysis.The micro-Doppler (m-D) effect induced by the rotating parts or vibrations of the target provides a new approach for target recognition.Analysis of micro-Doppler signatures V.C. Chen, F. Li, S.-S. Ho and H. Wechsler Abstract: 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.

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.
The analysis of micro-Doppler signatures in case of free and confined arm swinging was the core contributions seen within (11-13), where limited arm swinging or no arm swinging at all can be an indication of a person carrying objects or in hostile situations (hostages).
