基于组合权重的灰色目标威胁评估

Evaluation of Target Threat Based on Combinational Weigh and Grey Correlation

对空中来袭目标的威胁评估能为指挥员判断战场态势、合理分配火力单元提供有效的参考。目标的威胁评估需要得到雷达等传感器获取的相关信息,通过一定的算法,给出目标的威胁度排序。然而由于传感器获取的信息具有一定程度上的不确定性,完全依赖客观信息,往往与事实产生偏差。为此提出了一种主客观组合赋权的评估模型,对评估指标进行差异化赋权,在评估模型中加入指挥决策人员的经验影响,最后利用灰色理想关联法得到最终的威胁度排序。

The threat evaluation of airborne targets can be used to determine the situation of the battlefield and provide effective reference for the distribution of the fire units.Obtained by the radar and other sensors the threat degree of the target is given by a certain algorithm.However,because the information obtained by the sensor has some degree of uncertainty,it is always dependent on objective information,which often deviate from the facts.In this paper,an evaluation model of the subjective and objective combination is proposed,and the index is differentiated and empowered.In the evaluation model,the experience influence of the command decision maker is added,and the final threat ranking is obtained by using gray relationship analysis method.
