针对传统空战多目标威胁评估难以满足准确性$实时性的缺陷与不足!提出基于模糊集与证据理论相结合的空战多目标威胁评估方法% 该方法通过合理设置隶属度函数计算各威胁指标的威胁度基本概率赋值!使用改进的证据合成规则代替传统 组合规则对其进行指标间融合及时域融合&采用加权求和的方法计算空中目标的威胁值并排序.(Aiming at the shortcomings and deficiencies of traditional air combat multi-target threat assessment, which is difficult to meet the accuracy $real-time performance! A multi-target threat assessment method for air combat based on the combination of fuzzy sets and evidence theory is proposed. This method calculates the threats of various threat indicators by reasonably setting the membership function Degree basic probability assignment! Use improved evidence synthesis rules instead of traditional combination rules to perform inter-index fusion and time-domain fusion & use weighted sum method to calculate the threat value of air targets and rank.)
