提出一种三维空间中基于多普勒的改进修正霍夫变换快速航迹起始算法。利用传统航迹起始算法起始高超声速目标将导致目标容易丢失和虚假航迹增多，这不利于对高超声速目标的跟踪。文中提出的方法在三维空间中首先利用条件约束和多普勒信息辅助剔除部分虚假点，再利用修正霍夫变换法进行航迹起始。该算法不仅能有效起始航迹，而且极大地抑制虚假航迹。通过蒙特卡洛仿真实验表明，该算法能快速高效地起始航迹，是一种可行的临近空间高超声速目标的航迹起始算法。

An improved modified Hough transform track initiation method based on the Doppler knowl-edge in three-dimensional space is proposed.As for near space hypersonic target,the traditional track initia-tion leads to an increase in false tracks and is easy to lose tracks.The algorithm proposed in the paper uses constraints and Doppler information to eliminate part of clutters first,and then the modified Hough trans-form is applied.This method not only can make track initiation effectively,but also greatly decrease the false tracks.The Monte Carlo simulation shows that the method can initiate track fast and effectively and is a practical method for near space hypersonic target.
