基于霍夫变换的航迹起始方法研究

A track initiation method based on Hough Transform

介绍了霍夫变换用于航迹起始的典型方法。在对典型方法进行算法仿真的基础上,发现典型方法的两点不足。针对典型方法的不足,对原有的二值累积方法进行改进,有效解决了典型方法的分散累积现象。提出了一种新的虚假剔除方法。该方法不受目标距离方位值的影响。实验结果表明,对典型方法的改进是有效的。

The typical Hough transform method is introduced for track initiation.On the basis of the simulation of the typical method,two shortcomings are found.In view of this,the original two value accumulation method is improved to effectively solve the dispersing accumulation of the typical meth-od.A new false elimination method is proposed,and it is not affected by the range and azimuth val?ues of the targets.The test results show that the improvement of the typical method is effective
