Abstract

The micro-motion dynamics induce the micro-Doppler effect. The rotating motion of radar targets is introduced, the formulas of micro-Doppler for point-scatter model targets are derived, and some simulations for a warhead with a sphere-head cone is given in the paper. After geometrical modeling and meshing, the static RCS of the sphere-cone is calculated with PO+PTD. On the basis of the stationary modeling, a new method of quasi-dynamic electromagnetic modeling is provided. The time domain returned signal of coning warhead could be simulated in this method, after processing by time-frequency transform, the period of coning can be obtained. The simulation results are in agreement with the theoretical result. The method by geometrical model is more accurate than point-scatters model.
