针对岸基导弹对敌突防过程中可能面临的各类威胁源进行了量化分析,根据各威胁源的性能、特点在三维空间构建了地理障碍威胁、平台障碍威胁、恶劣气象威胁、敌防空火力与电子干扰系统威胁等不同威胁源的威胁概率函数模型,模型函数能连续、完整地表述威胁值的变化状态。在分析影响岸基导弹航迹规划因素的基础上,建立了岸基导弹航迹预规划的目标函数模型,并进行了仿真实验,仿真结果校验了所构建模型的有效性。 Aiming at the various types of threat sources that may be faced in the process of surface-to-air missiles’ strike-and-miss process, we quantified and analyzed the types of threats that might be faced during the process of surface-to-air missile penetration. According to the performance and characteristics of each threat source, we constructed the geographic obstacles, threats to platforms, And threatening sources such as threat of electronic jamming system, the model function can describe the changing state of threat value continuously and completely. Based on the analysis of the factors that affect the trajectory planning of shore-based missile, the objective function model of pre-planned shore-based missile trajectory is established and the simulation experiments are carried out. The simulation results verify the validity of the proposed model.
