| 摘 要： | 为了提高地面运动目标跟踪精度,提出了基于地理信息约束的变结构交互多模(VS-IMM)的目标跟踪算法。通过建立地理信息系统约束地面目标运动状态,并利用目标转弯曲线模型确定滤波器中机动目标的时变运动模型集,采用地理信息约束的变结构交互多模算法可更符合实际进行地面目标机动跟踪。针对机场地面机动目标的仿真结果表明,给出的地理条件约束的目标跟踪算法比现有交互多模算法具有更好的性能。

| Abstract: | To improve the ground maneuvering target tracking accuracy, a variable struc
ture interaction multiple model(VS-IMM) target tracking algorithm based on t
he geographic information constraints is proposed and evaluated. Firstly, the ge
ographic information restrictions are included in both target observation and dyn
amic models to obtain the target state estimates. Then, the time-varying target
maneuvering model set can be derived from the curvilinear model of the filter.
Finally, the VS-IMM algorithm using geographic information constraints can be ap
plied for the ground maneuvering target tracking more practically. Simulation re
sults show that the proposed algorithm has a better performance than the existing IMM
maneuvering target tracking algorithm for the airport maneuvering targets. |
