TLDR
The received signal is decomposed into a family of parametric basis signals that are dependent of the target angular velocity, and the significant coefficients of the sparse solution indicate the initial phases and the Doppler amplitudes of Micro-Doppler components.Abstract:
A method of Micro-Doppler component separation based on parametric sparse time-frequency representation is proposed in this paper. The received signal is decomposed into a family of parametric basis signals that are dependent of the target angular velocity, and the significant coefficients of the sparse solution indicate the initial phases and the Doppler amplitudes of Micro-Doppler components. The performance of the proposed method in terms of Micro-Doppler component separation is evaluated by simulations.read more

Application of adaptive chirplet representation for ISAR feature extraction from targets with rotating parts
TL;DR: The problem of feature extraction from inverse synthetic aperture radar (ISAR) data collected from targets with rotating parts is addressed and point-scatterer simulation results show that better geometrical features of the body and better micro-Doppler Features of the rotating part can be extracted after the separation.
