不完全信息下目标威胁等级判断模型

摘要

针对目前威胁等级判断模型在目标属性值缺失时不能进行有效判断的问题，提出利用已知数据来等比例替代未知数据的方法，并且依据模糊识别算法建立威胁判断模型。此外，分析了影响空中目标威胁判断的指标，结合实例分析表明了该模型的实用性。%According to the problem that the present threat level judgment model cannot do the effective evaluation on partial unknown attribute value,a method used to know data to proportion alternative the unknown data is shown,and a threat judgment model is established by using fuzzy identification theory. Besides,the criteria which effects the aerial targets threat level judgment is analyzed,tests show that this method is satisfactory with possesses good practicality.
