摘要:: 针对多机协同多目标攻击( MFCMTA)空战特点，文中提出了基于模糊D-S证据理论的MFCMTA空战态势评估方法。首先，根据模糊集理论和D-S证据理论可以相互取长补短的特点，分析了模糊集理论和D-S证据理论融合的方法，并对mass函数进行了分析计算。其次，对MFCMTA空战的态势评估事件进行分类和提取，对发生事件的状态进行量化。针对态势评估中的不确定性问题，用模糊逻辑对目标事件进行检测，建立了事件检测的模糊逻辑模型，然后引入D-S证据理论，将模糊D-S证据理论应用于MFCMTA态势评估，找出事件与态势假设之间的潜在关系，并根据目标的行为序列来逐步推断其意图，建立了基于模糊D-S证据理论的MFCMTA态势评估模型。最后，给出了算例分析。算例结果表明推理算法和知识表达方式合理，所建立的模型合理有效，是一种有效解决态势评估问题的应用模型。

Abstract:: Aiming at characteristics of MFCMTA air combat,a new Situation Assessment ( SA) method for MFCMTA air combat is pro-posed based on fuzzy D-S evidence theory. Firstly,fuzzy theory and D-S evidence theory are complementary,so their fusion methods are analyzed. At the same time,mass function is analyzed and calculated. Secondly,events of SA in MFCMTA air combat are classified and extracted,and the status of happened events are quantified. Aiming at the uncertainty in SA,events are tested by fuzzy logic,and fuzzy logic models of events test are constructed. Then,D-S evidence theory is introduced,and fuzzy D-S evidence theory is used to SA in MFCMTA air combat. The potential relationship between SA and events is found out,and their intentions are gradually deduced according to behavior sequences of the target. What’ s more,the SA model for MFCMTA air combat is constructed based on fuzzy D-S evidence theory. Finally,the example analysis is given. The numerical example results show that reasoning algorithm and knowledge expression is reasonable,and the established model is reasonable and effective,which is an effective application model.
