| 摘 要： | 首先建立了纯方位目标跟踪系统的动态模型和一个最小二乘估计器,分析了该系统的完全可观测性。在系统完全可观测的条件下,引入可观测程度这一概念。文中定义了两种描述系统可观测程度的方法。它们都很好地反映了系统可观测程度随跟踪时间的变化过程。研究发现,纯方位目标跟踪系统往往是弱可观测系统,这正是系统跟踪效果不佳的原因所在。然而,文中表明的系统可观测程度同跟踪几何态势关系密切这一事实,又使得从己艇机动入手解决跟踪效果差的问题成为可能,就是通过极大化系统的可观测程度优化己艇的机动策略。

| Abstract: | A least squares estimator for bearings-only target tracking system isdeveloped and the observability of the system is analyzed.For a completelyobservable system,the concept of observability(DOO)is introduced for deeperdescribing of its essences.From two definitions of DOO given in this paper,bearings-only tracking system is seen to be a weakly observable system whichoften leads to imperfect tracking results.The close connection between DOO andthe tracking geometry uncovered here,however,makes it possible to improve theresults by changing own warship motion,i.e.,optimizing own-ship maneuveringstrategies through maximizing the DOO of system. |
