Mirco‐motion analysis of ballistic targets is a useful tool for discriminating different targets in the aerospace. A micro‐motion model combining inertial parameters with a target radar coss‐section is presented. The relation between target micro‐motion states and inertial parameters is deduced. By using the time‐frequency transform method, the micro Doppler spectrogram is obtained. Simulation results show that the proposed method can be used for evaluation of ballistic targets recognition and discrimination.
