| 摘 要： | 通过对目标的不确定机动分析和对不确定机动的模式分类(非机动、临界机动、弱机动、强机动),建立了一种新的目标状态自适应估计器——交互作用的双自适应模型估计器。它通过具有机动识别特性的二阶自适应模型和具有机动水平特性的三阶自适应模型,以及它们之间交互作用自适应组合方式的结合,达到了跟踪估计目标各种运动的“全面”自适应能力。应用新估计器对目标的5种基本运动进行了Monto-carlo仿真。仿真表明,它具有所期望的良好性能。

| Abstract: | The uncertain maneuver of a target is analysed and divided into four modes: non-maneuver, critical maneuver, weak maneuver, and strong maneuver. Based on that, a new adaptive estimator of target state - the interacting dual adaptive models estimator is set up. With the combination of a 2nd - order adaptive model of maneuver detection and a 3rd -order adaptive model of maneuver level and a way of the interacting adaptive combination, it reaches "all-round" adaptive ability of tracking the various motions of a target. The new estimator is used to track the five elementary motions of a target in Monto-Carlo simulation. The simulation shows that the estimator has the expected performance. |
