摘要

摘要: 基于微多普勒效应理论的弹道目标3维成像与3维微动特征提取技术可为目标识别，导弹防御提供重要特征信息。该文将干涉式逆合成孔径雷达(InISAR)中多天线干涉处理的思想引入到弹道目标3维成像与3维微动特征提取研究中，将微多普勒效应理论与多天线干涉处理技术相结合，重构出散射点在各时刻的3维坐标，实现弹道目标的真实3维成像，并在此基础上解算出弹道目标的微动参数与结构参数。仿真实验验证了所提方法的有效性与鲁棒性。

Abstract: 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.
