测向交叉定位系统的动态航迹起始算法

提出了一种两站测向交叉定位系统多目标跟踪的动态航迹起始算法。该算法根据启发式规则消除一部分虚假定位点,用Hough变换法检测出所有直线航迹,再利用逻辑法起始真实目标的航迹。对存在虚警、漏检和目标数量未知的复杂环境的仿真研究,证明了该算法的有效性。讨论了新算法由两站系统推广到多站系统的方法,避免了多站测量数据关联的NP完全问题。

A Dynamic Track Initiation Algorithm for Passive Bearing-Crossing Location Systems

A new dynamic multitarget track initiation algorithm for two direction-finding location systems was presented:a part of false intersection points were first eliminated by some heuristic rules, then all straight tracks were detected by Hough transform, and the true tracks were finally initiated by logic-based methods. Its high efficiency is confirmed by simulations in real complex environment where exist false alarms, missed detections and an unknown number of targets. At the end, the method of extending the presented algorithm from two-observation systems to multi-observation systems was introduced and then the NP-complete problem of associating measurements from multiple passive sensors is avoided.
