基于改进非参量法的现代空战威胁评估研究

Study on Improved Non-Parameter Model Based Threat Assessment in Modern Air Combat

针对现有威胁评估非参量模型的不足,提出一种改进的非参量法模型。该模型结合对现代空战过程和影响参数的分析,充分考虑现代空战的特点,构造了参战双方战机的态势、效能、事件、目标战役价值等优势函数,优化了方位角、进入角、距离、能量、效能等优势函数然,并将事件、目标战役价值作为威胁评估的因素,采用熵权法求得权重系数后,线性加权法将各优势函数综合,求得总体优势函数。最后,对优化、改进的非参量法模型进行仿真,仿真结果表明,该模型更符合超视距空战的实际,并且对现代空战威胁评估合理、有效。

In order to overcome insufficiency of non-parameter models for threat assessment, an improved non-parameter model is proposed. Through analyzing modem air combat process and impact factors, and thoroughly con- sidering features of modem air combat, superiority functions such as situation of friend and hostile aircrafts, efficiency, event, value of campaign are established, superiority functions such as azimuth, approaching angle, distance, energy and efficiency are optimized; through taking the event and value of target campaign as factors for threat assessment in the improvement model, weight coefficients is obtained by using of entropy weight method ; and finally general superiority function is deduced by synthesizing all superiority functions with the weighted linear method. Optimized and improved model is simulated, simulation results verified that the model is more suitable for over- the-horizon air combat and can provide reasonable and effective threat assessment.
