基于运动状态的航迹起始算法研究

Study on Approaches for Track Initiation Based on Dynamic States

针对传统的基于逻辑的航迹起始方法在量测扩展过程中存在的弊端,提出了基于目标运动状态的航迹起始算法,并给出了更为精确的起始波门构造方法。利用目标的位置信息形成候选目标航迹,在候选目标航迹扩展过程中,采用提出的修正Hough变换提取目标状态信息,并根据目标的状态信息对候选航迹进行检验。仿真结果表明,该算法比其他基于逻辑的方法有更低的虚警概率,并且对存储空间要求低,适于工程应用。

Aiming at the shortcomings of traditional logic based approach for track initiation,a novel track initiation algorithm based on target dynamic states is developed,and a new tracking filter initial gate is given. The algorithm firstly formes the candidate tracks using position measurements, then testes the candidate tracks by the target dynamic states acquired by modified Hough method. The simulation results indicate that the presented approache has lower false probabilities of track initiations than other methods based on traditional logicbased approach, and that the memory requirement is lowered efficiently.
