摘　　要：为了分析逻辑法起始的性能,采用Z变换或人工枚举的方式只能分析窗口长度较小时的性能。为了抑制虚假起始,对海面目标自动起始时往往需要更长的窗口。基于二叉树模型,提出了采用先根方法构造二叉树并产生所有事件组合的方法,进一步基于马尔科夫过程获得了一组常用逻辑法的各扫描周期航迹起始的概率、航迹起始所需的扫描周期数的平均值和标准差。本方法可方便地拓展到对更长窗口长度的逻辑法起始性能进行分析。In order to analyze the performance of initiation of the logic method,the Z-transform or artificial enumeration method can only analyze the performance when the window length is small.In order to suppress false initiation,a longer window is often required for automatic initiation of surface targets.Based on the binary tree model,a method of constructing the binary tree by using the preorder method and generating all event combinations is proposed.Based on the Markov process,the probability of track initiation of each scan period and the average value and standard deviation of the number of scan cycles are further obtained for a set of common logic methods.The method can be easily used to analyze the initial performance of the logic method with longer window.
