摘要
空中目标威胁评估是现代战争的重要环节,D/S证据理论具有多数据源不确定信息推理和融合特点,符合人类思维决策过程。根据空中目标判断准则建立威胁评估指标体系,利用区间分布的基本可信度函数模型代替隶属度函数目标威胁模型,并给出了基本可信度函数值的归一化计算方法,使之符合D/S证据理论可信度分布函数要求,并用实例对模型进行了验证,结果表明D/S证据理论是评估空中目标威胁的一种有效方法。
Threat assessment of air targets is an important part of modern warfare.D/S evidence theory is characterized by reasoning and integration of uncertain information from multiple data sources,which accords with the decision-making.According to air target threat judgment criteria established evaluation index system,us‑ing basic probability function model of interval distribution instead of the membership functions of target threat model,and gives the basic probability function value of normalized calculation method,to make it conform to the requirements of the D/S evidence theory is an effective method to evaluate the threat of air targets.
