摘要
围绕弹道导弹多目标跟踪中的数据关联问题,分析了MHT算法的关联假设构建及概率计算的基本过程;而后为降低关联假设概率计算的复杂度,提出了基于线性分配方法(LAP)的MHT关联假设构建方法;仿真表明基于LAP的MHT算法对邻近发射和轨迹交叉的多弹道导弹目标具有较好的跟踪能力,进一步通过设置距离门限,该算法对变加速度的弹道导弹目标亦具有良好的跟踪能力。
On the problem of multitarget tracking of ballistic missile, the basic process of the rele- vance hypothesis establishi in order to reduce the com ng and its probability calculation for MHT arithmetic are analyzed firstly; then plexity of relevance hypothesis probability calculation, linear assignment pro- gramming （LAP） is introduced into the relevance hypothesis establishing for MHT arithmetic. The simu- lation result indicates that the MHT arithmetic based on LAP is good for the ballistic missiles tracking which are launched closely or orbits are intersecting. Furthermore, if the distance threshold is set, the a- rithmetic is also good for
