Micro-Doppler analysis and application of radar targets

Radar target micro-Doppler signatures reflect the electromagnetic characteristics, geometry structures and motion signatures of the target, which has been shown to be promising signatures for application. In this paper, we review the present research status and some key techniques in this field, including the analysis of micro-Doppler signatures, feature extraction and the applied fields. Several future research directions for micro-Doppler signatures are discussed at the end of this paper.
