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。
Spin-target 3-D imaging is of great importance for spatial object recognition. In order to solve the problem of the unmanageable three-dimensional structure feature of a single-target radar, a three-dimensional imaging method of spin-target wideband radar based on fretting correlation is proposed. By using multiple radars to acquire echo signals of different perspectives, the multi-scattering centers of different radar echoes are obtained based on the characteristics of micro-Doppler information of each scattering center at the target spin, Real dimensional 3-dimensional image. Simulation results show the effectiveness and robustness of the proposed method.
