摘要：

The micro-Doppler (m-D) signature, which induced by micro-motion dynamics, plays an importance role in radar target recognition, so it has been paid a great attention in the radar fields. For rotor blades, the scattering point distribution, i.e. the uniform distribution and the nonuniform distribution, has great influence on the m-D signature. Influence about rotor scattering point's distribution on micro-Doppler signature is studied in this paper. Firstly, the mathematic model based the backscatter coefficients and the scattering point distribution on blades was built. Secondly, the influence of the scattering point distribution on the m-D signature associated with the cross range resolution and the time-frequency representation (TFR) was analyzed. Finally, simulation results show the proposed model and the analysis about the influence are available.
