| 摘 要： | 针对逻辑航迹起始算法不能有效剔除V字形的航迹,提出了一种基于目标运动特性的逻辑航迹起始方法。其主要思想是在逻辑法航迹起始阶段,利用三角函数式求解三个相邻时刻点的夹角,根据目标的运动特性,此夹角一般大于90°,因此通过对夹角进行限制,可以有效剔除与航迹成V字形的测量点迹。仿真结果表明,该方法可以有效地在杂波环境中快速起始航迹,具有较好的实用价值。

| Abstract: | Aiming at the low efficiency of the conventional logic-based track initiation methods on eliminating V-shape tracks,this paper presents a new track initiation method which makes use of the characteristics of the moving targets.In the new algorithm,the trigonometric functions are adopted to obtain the inclination of three adjacent points,which is usually larger than 90°,and a limitation condition on the inclination is added to the conventional logic-based track initiation process so as to exclude the returns which may form V-shape tracks.Simulation results show that the new track initiation algorithm can effectively and quickly initiate tracks in clutters,which may have good practical values. |
