摘　　要：针对天波雷达作战效能评估涉及因素众多且具有不确定性特点,提出了基于证据理论的天波雷达作战效能评估方法,建立了天波雷达作战效能评估指标体系。基于同时修正证据源和证据合成规则的思想,提出了一种新的相似度度量方法,给出了新的证据权重确定方法,并结合修改的证据合成规则,提出了一种新的冲突证据合成算法,将其应用于定性指标融合。再利用证据合成公式将定性和定量指标进行综合,得到最终评估结果。实例表明,该方法评估结果符合实际,为天波雷达作战效能评估提供了新的思路。According to the characteristics of many factors and uncertainty for operational efficacy e- valuation of sky-wave over-the-horizon radar （SWOTHR） , an efficacy evaluation method is proposed based on evidential theory. Firstly, the operational efficacy index system is established. Secondly, a new algorithm dealing with evidence combination rules ly conflict evidences is proposed based on the idea of improving evidences and together, which is applied to synthesize the qualitative indexes. In the new al- gorithm including an improved evidence combination rules, a new method to calculate the similarity be- tween evidences and a new method to ascertain weight of evidences are proposed. Finally, the paper com- bines The p the quantificational and qualitative indexes with evidence combination rule to get the target result ractical example shows that the result conforming to the fact and the method provides a new idea to evaluate the operational efficiency for SWOTHR
