By taking the rotary symmetrical cone-cylinder warhead as an object of study, this paper sets up a model for the precession of target model, deduces the micro-Doppler theoretic formulas for various scattering centers and gives a micro-Doppler scheme for simulation of precession target based on static electromagnetic scattering data. And finally, the simulation experiment is performed on micro-Doppler of precession target, and the correctness of theoretic analysis and its simulation are proved in this paper. Experimental results show that the simulation of micro-Doppler based on electromagnetic scattering data can reflect the more realistic scattering mechanism of target, thus laying a basis for extracting and recognizing effectively the features of subsequent ballistic target.
