The Three-Dimensional (3-D) imaging and 3-D micro-motion feature extraction techniques for ballistic targets based on the micro-Doppler (m-D) effect theory can provide significant information for target recognition and ballistic missile defense. The idea of multi-antenna interferometry processing from Interferometric Inverse Synthetic Aperture Radar (InISAR) is introduced into the 3-D imaging and 3-D micro-motion feature extraction of ballistic targets in the paper. Based on the integration of m-D effect theory and multi-antenna interferometry processing technology, the true 3-D image of target is obtained. The parameters of micro-motion and target structure are extracted by utilizing the reconstructed 3-D coordinates of target. Simulations are given to validate the effectiveness and robustness of the proposed algorithm.
