低概率目标点迹截获下的修正Hough变换航迹起始方法

A Track Initiation Method Based on Hough Transform for Low Probability Target Track

为了在强杂波的环境下有效地起始航迹,提出一种针对低概率目标点迹截获下的修正Hough变换方法。该方法使用标签记录回波数据的时序信息,并通过速度门限和时序特征信息对截获的数据进行关联,同时结合Hough变换的方法,可以在低概率目标点迹截获下实现航迹起始。仿真实验表明,算法有效地克服了现有的Hough变换法及其衍生改进算法不能有效地解决低概率目标点迹截获下的航迹起始问题,大大提升了起始正确率,并具有较强的工程可行性。

To find an efficient track initiation method in the strong clutter environment, a track initiation method is proposed based on Hough transform for low probability target track. The pro- posed method records the target echo sequential information using labeled data, to find the rele- vance of continuous or discontinuous data with the speed threshold and time-order character based on Hough transform. Compared with other relevant methods, the simulation results show that the proposed method has a great performance in strong clutter environment with low proba- bility target track. It has a great improvement in track initiation performance and speed, and it has a engineering feasibility and is suitable for real application.
