摘　　要：针对三维空间中的强杂波环境和目标低概率截获情况,现有的顺序数据处理方法和批数据处理方法均无法做到没有虚假航迹且能准确起始正确航迹,文章提出一种改进后的基于随机Hough变换的新方法,用于三维空间中的航迹起始。在传统二维Hough变换的基础上,该方法将参数空间扩展到三维,并利用速度门限和周期时序特性进行关联。仿真结果表明,其算法能有效解决强杂波、低截获环境下的三维航迹起始问题。The existing track initiation methods based on sequential processing and batch processing cannot perform effectively in strong clutter environment with low probability target track in 3-D space.Based on this problem,a modified track initiation method in 3-D space based on randomized Hough transform is proposed in this paper.This method is an extension of the tradition 2-D Hough Transform which uses target velocity and and time-order character to limit valid data.Simulation results show that this method has great performance in strong clutter environment with low probability target track.
