中文摘要：

针对空战目标威胁评估问题，提出了一种新的基于区间支持向量回归的评估方法。首先对空战目标威胁评估方法中常用的距离威胁模型进行了分析，在此基础上对距离威胁模型进行了改进。然后构建了基于区间数方法的威胁评估指标权重的确定方法。最后建立了基于区间支持向量回归的空战目标威胁评估模型，并进行了仿真实验。仿真结果表明，提出的方法具有较高的预测精度，能够准确、快速地完成多个空战目标的威胁评估。

英文摘要：

A new assessment method based on interval support vector regression is proposed with regard to the problem of target threat assessment for air combat. First,distance threat model is analysed which is regularly uesd in target threat assessment methods for air combat,based on which distance threat model is improved. Second,the ascertaining method for solving weights of threat assessment indexes baesd on intervals is established. Finally,the model of target threat assessment for air combat is proposed based on interval support vector regression,and then carryed on an simulation experiment. The simulation results show that the method proposed has high level of precisioin,which can accomplishes multi-target threat assessment for air combat fleetly and exactly.
