摘要
根据导弹在突防中遇到威胁,针对现有航迹规划威胁建模方法对专家经验和先验知识过于依赖,无法反映攻防对抗过程中动态威胁因素对突防效果的影响,为提高航迹效率和精度,提出一种基于仿真数据的威胁计算模型。通过引入空间威胁度的度量指标和若干影响突防效果的时间相关参数,利用攻防仿真得到的分析统计数据构造计算空间威胁度的解析表达式,生成空间威胁态势。通过一个算例证明模型不仅计算速度快,而且计算结果具有良好的可解释性,能够更准确地描述各种威胁对导弹最终突防效果的影响规律。
To avoid the over dependence on experts and transcendental knowledge during threat modeling for path planning,a simulation data based threat modeling method is presented to describe the dynamic threat existing in the process of the countermeasures. By means of simulation,parameters associated with time which influences the penetration are introduced into the threat model. The connection between these parameters and the position of the missile is made. An application of the model is given to prove the superiority of this model compared with other threat calculation model without simulation data support. This model can describe the threat during the penetration more precisely and provide an explicable and quick threat evaluation for path planning.
