自旋目标3维成像对于空间目标识别具有重要意义。为了解决单基雷达中无法获取自旋目标真实3维结构特征的问题，该文提出一种基于微动特征关联的自旋目标宽带雷达3维成像方法。通过利用多部雷达获取目标在不同视角下的回波信号，基于目标自旋时各散射中心的微多普勒信息特征实现不同雷达回波数据的多散射中心关联，获得了能够反映自旋目标真实尺寸的3维像。仿真结果验证了该方法的有效性和鲁棒性。

The spinning targets’ three-dimensional (3D) radar imaging is one of the most significant studies for space targets recognition. To obtain the real 3D characteristics of the targets that can not be acquired from a monostatic radar, a broadband 3D radar imaging algorithm based on micro-motion parameter correlation of several radars towards the same spinning target is proposed. Based on scattering centers’ micro-motion parameters differences in different radars, the scattering centers in echoes from radars respectively of the same target are correlated, and the 3D radar image of the target is obtained which corresponds with the real size of the target. The simulations confirm the effectiveness and robustness of the algorithm.
