机动目标跟踪中的多模算法

The multiple model algorithm in maneuvering target tracking

机动目标跟踪是一个很具有挑战性的任务 ,即使是跟踪单目标也可能因为目标的逃避机动而失跟。机动目标跟踪所遇到的基本问题是所建目标模型的动力学方程与目标的实际运动模式存在着不匹配。所以很多学者研究多模算法来解决这一问题。本文对学者们在多模算法上的研究结果进行了系统总结分析 ,得出结论 :变结构的方法是提高跟踪性能、减少运算量 。

The maneuvering target tracking is a challenging task. Even if in single target tracking, it is likely to miss the target because of the escape maneuver of the target. The most important problem in maneuvering target tracking is the mismatching between the targets' moving modes and the equations built to describe the target mobility. Many scholars tried to solve this problem with multiple model algorithms. In this paper, multiple model algorithms are analyzed and conclusions are given that the variable structure multiple model algorithm is a useful algorithm, which could improve the performance in target tracking, simplify the computation, and make it possible to use the MM algorithm in practical maneuvering target tracking.
