根据天波超视距雷达的作战任务和战技术性能,建立了天波雷达作战效能评估指标体系。针对天波雷达作战效能评估涉及因素众多且具有信息模糊和不确定的特点,提出了一种基于云模型和证据理论的天波雷达作战效能评估方法。该方法运用折扣证据融合规则合成专家意见实现权重和定性指标值确定,并将权重和指标值转化为云模型,再按云运算规则进行层次运算得到最终评价结果。实例表明,该评估方法有效可行,为天波超视距雷达的作战效能评估提供了新的思路。

According to the operational mission and performance of tactics and technique for sky-wave over-the-horizon radar(SWOTHR), the operational efficiency evaluation index system for SWOTHR is established. Aiming at the characteristics of involving many factors with information fuzzy and uncertainty for operational efficiency evaluation of SWOTHR, an new operational efficiency evaluation method is pntforward based on cloud model and evidential theory. In the method, discount evidence combination rule is used to combine experts’opinion to ascertain weights and qualitative index values. And then, weights and index values are converted to cloud model and calculated as hierarchies based on cloud calculation rules until getting the target result. The result shows that the method is useful and feasible, which provides an new idea for operational efficiency evaluation about SWOTHR.
