【摘要】：为解决空中编队目标跟踪过程中航迹关联的难题,提出一种基于目标运动状态的自适应相关波门算法。首先通过分析编队目标的运动特征,完成编队分割和编队速度的估计;然后将编队目标的速度方向作为约束自适应波门的条件,在跟踪过程中根据目标运动方向确定波门方向,并基于前一时刻编队中各目标的距离来选择波门尺寸,同时考虑测量误差和预测误差的影响。仿真结果表明:相对于传统的固定波门算法,在编队目标跟踪过程中,自适应波门算法在避免编队内目标航迹相互交错和保证跟踪稳定性方面可以达到较好的跟踪效果。
[Abstract]:In order to solve the problem of track correlation in air formation target tracking, an adaptive correlation-gate algorithm based on target motion state is proposed. Firstly, formation segmentation and velocity estimation are accomplished by analyzing the motion characteristics of formation targets. Then, the velocity direction of formation target is taken as the condition of constrained adaptive wave gate, and the direction of wave gate is determined according to the moving direction of target in the tracking process, and the size of wave gate is selected based on the distance of each target in the formation at the previous moment. The simulation results show that compared with the traditional fixed gate algorithm, in the process of formation target tracking, the effect of measurement error and prediction error is considered. The adaptive wave gate algorithm can avoid the interlacing of target tracks in formation and ensure the tracking stability.
