摘要
无源交叉定位系统在现代抗干扰中有着广泛的应用,其中多目标定位中虚假定位点的去除是一个长期困扰研究者的难点.针对被动传感器测向交叉定位系统对多目标的跟踪问题,分析了多目标交叉定位虚假交叉点(鬼点)的分布特点,建立了基于Hough变换的多目标跟踪模型,通过Hough变换鬼点判决实现了单个观测周期大多数鬼点的去除,通过Hough变换逐层分离实现了航迹的起始,并在此基础上通过滤波完成了多目标的跟踪.仿真结果表明,该方法对鬼点的剔除率较高,对目标的跟踪精度较高.
Passive location system is widely used in anti-interference,in which false intersection deleting is one difficulty that has puzzled researchers for a long time.Towards solving the problem of multi-target tracking in triangulation system with passive sensors,the essay analyzes the distribution of false intersections and builds a multi-target tracking model based on the Hough transform.Majority of the false intersections of each observation period are deleted using the Hough judgment.Track initiations can be realized using the Hough transform by separating them story by story.Then,multi-target tracking is realized by filtering.Simulation results show that the model above can delete false intersections with higher efficiency and the tracking precision is higher.
