防空系统中空中目标威胁评估方法研究

针对当前对空中目标威胁评估研究的不足，提出了一种防空系统中评估目标威胁度的新方法，其思想在于将空中目标的威胁因子分为定量指标和定性指标，其中定量指标包括目标速度、目标高度等可以直接获取的指标，该部分指标通过隶属函数直接得到威胁值；定性指标包括目标类型、目标意图等不能直接获取的指标，通过贝叶斯网络进行推理以得到静态威胁值。最后通过AHP 方法对各个指标威胁值进行加权得到总威胁值。该方法的特点在于定性分析与定量分析的结合，通过仿真算例验证了该方法的有效性与可行性。

Threat Assessment of Aerial Targets In Air-Defense

In order to solve the insufficient about target threat assessment among the existing literature, a new method to as?sess the targets’ threat is proposed in this article. The ideology of this method is to classify all the threat indexes into the quantitative indexes and qualitative indexes, while the quantitative indexes includes the indexes which could be obtained di?rectly such as targets’ velocity, targets’ height, and the membership functions are employed to calculate the index values;the qualitative indexes includes the indexes which could not be obtained directly such as targets’ type,targets’ intent and so on, so the Bayes Network is applied to handle these indexes to acquire the static threat value. Finally, all the threat values are calculated weighting through AHP method in orde to acquire the targets’ total threat value. The characteristic of this method is to combine the quantitative indexes and qualitative indexes effectively, meanwhile the simulation examples verify the effectiveness and feasibility of this proposed method.
