一种基于区间数的空中目标威胁评估技术

Aerial targets threat evaluation technology based on interval-number

针对现有空中目标威胁评估方法存在的不足,提出了一种基于决策心态指标的区间数评估技术,讨论了目标机动对威胁度的影响,给出了评判矩阵和权重分配的有界区间表示及目标威胁度排序方法。最后举出一个应用实例,并将该方法排序结果与基于可能度的中转法排序结果进行了比较。实践证明,该技术评估结果准确,能有效减小误差。

Considering the existing aerial targets threat evaluation is not fully ideal, an interval-number evaluation technology by index of attitude is presented, and the effect of target manoeuvre to threat degree is discussed. The limited close interval-number of evaluation matrix and weight distribution is put forward, and the ranking method of target threat degree is given. Finally, an application case is given, and the ranking results of this method is compared with middle translation method. It can be shown that the result of this evaluation technology is correct, and can decrease the error efficiently.
