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.
