摘要
散射中心关联是雷达目标三维重构的关键技术,由于目标散射中心在连续观测视角下在序列图像间的运动轨迹及散射强度具有强相关特性,因此根据相关性建立的双重隐马尔科夫模型能够鲁棒地表征序列图像间散射中心关联状态的变化。大量的实验结果表明,该算法能够实现散射中心的鲁棒关联。
Scatters correlation is a key technology to 3D reconstruction of radar targets. A novel method based on double hidden Markov model （HMM） can describe the change of scatters correlation status robustly between ISAR images due to the strong consistency of moving trace and amplitude of scatters under the continuous aspect angles. Numerous test results show that the algorithm carl perform scatters correlation robustly.
