摘要：

基于目标三维散射中心在雷达视线上的几何投影关系,提出了一种雷达目标散射中心关联和三维成像的新方法,采用随机抽样一致性方法实现了对关联样本有效性的检验以及对各散射中心最优关联方案的选取。仿真实验表明,该算法简单易行,适用于目标散射中心和姿态数目较多的情况,并可以对存在缺失点、虚假点等复杂情况的散射中心进行关联和三维成像,具有较高的鲁棒性。

Abstract:

Based on the geometrical projection of 3D scattering centers on the line of radar sight, a new method of scattering centers association and 3D imaging of radar targets is proposed. The random sample consensus (RANSAC) method is utilized to examine the validity of the associated samples and select the optimal associated scheme of each scattering center. Simulation results show that the proposed algorithm, which has higher simplicity and robustness, is applicable for the cases with more scattering centers and numbers of attitude, and is able to be applied in the association and 3D imaging for scattering centers existing missing and fault points.
