不确定空情信息条件下的意图识别方法

态势理解是根据态势觉察生成的态势特征向量,结合领域专家的军事知识对当前态势进行解释,对敌方意图和作战计划进行识别的过程。现代防空作战的战场环境变得越来越复杂,获得的空情信息是不确定的,因此对敌空袭意图的有效识别是C4ISR系统中的一个关键问题。用区间数来表示不确定的空情信息,给出了区间数与实数的距离公式;通过方位角、距离、水平速度、航向角、高度来描述目标的作战意图,建立了基于区间数灰色关联分析的不确定空情信息条件下的意图识别模型;将待识别意图的目标作为比较序列,已知作战意图的基准特征值向量作为参考序列;通过模糊聚类分析计算意图识别中基准特征值。实例表明了方法的有效性,可为防空作战指挥决策提供依据。

A method of Inference Intention with Uncertain Aerial Information

The purpose of situation understanding is to identify the intention and warfare plan of enemy,which explains the current situation based on the expert knowledge and situation character vector.The battlefield circumstances in the modern aerial defence warfare become more and more intricate,and the aerial intelligence obtained is uncertain,so the effective inference of intention of the air attack is an important problem in the C4ISR system.In this paper,the uncertain aerial intelligence is expressed by the interval number.The distance formula between interval number and real number is presented.The target intention is described by the characters of position angle,distance,horizontal speed,course angle and height.Then the inference of intention model based on interval number grey relationship analysis with uncertain aerial intelligence is built.Taking the target intention to be inferred as the comparative sequence,and the known normal character vector as the reference sequence,the normal character number can be calculated by the method of fuzzy cluster analysis.The validity of this method is demonstrated by an example,which can provide scientific basis for the command decision making in the aerial defence warfare.
