| Abstract: | Based on the micro-Doppler,a target micro-motion resolution method is examined.By means of Wigner-Ville Distribution,a micro-Doppler extraction approach is presented.Then with the filtering of micro-Doppler,a target micro-motion resolution technology is proposed,in which the target micro-rotation resolution and micro-translation resolution are implemented via the Fourier transform of micro-Doppler and micro-Doppler rate.Monte Carlo simulations with synthetic data demonstrate the performance of the target micro-motion resolution technology,and the simulation results confirm the effectiveness of the technology. |
