超视距空战的威胁估计

Threat Evaluation in Beyond-Visual-Range Air Combat

摘要:

针对现有超视距空战威胁估计模型的不足,提出了一种新的基于模糊逻辑的超视距空战威胁估计模型。该模型以机载中远程空空导弹攻击区、雷达搜索区性能参数以及双方战术几何关系、相对运动趋势作为评估对象进行模糊化,设计了角度优势、距离优势推理模块,并以二者的加权和作为当前空战态势的优势指数。模型较为全面反应了空战态势与参战飞机的作战能力,可为超视距多机协同攻击多目标空战时的目标分配、战术选择提供参考。仿真结果验证了模型的有效性。

Abstract:

To cope with the shortage of the existing Beyond-Visual-Range air combat threat evaluation model, a new threat evaluation model based on fuzzy theory is proposed, which takes into accounts the air-based BVR (Beyond-Visual-Range) weapon systems effectiveness that can affect the BVR combat effectiveness, such as medium-long range air-to-air missile attack area parameter and radar effectiveness parameter. Tactics geometry situation and the movement tendency are also calculated. Fuzzy inference blocks are designed to calculate the advantage in angle, distance, and its weighed average is treated as the whole superiority index of current air combat situation. The model describes current air-combat situation well and can be used as the inference of distribution of multi-targets attacking or tactical choice in BVR air combat. A simulation result gives credits to the model.
