时间最优的直升机对海攻击导引方法研究

Study on Minimum-time Attack Trajectory of Helicopter in Sea Warfare

就一架舰载直升机与多艘导弹艇的对抗攻击建模问题进行了研究,目的在于用最短的时间将舰载直升机导引到有多艘导弹艇的作战区域。文中在运用微分对策理论的同时结合了局部优化的思想,建立了攻击时间尽可能短的数学模型,进而推导出了对抗多方为达到各自作战目所应采取的最优控制策略,并给出了实现步骤与方法。最后,对一架舰载直升机与两艘导弹艇的对抗进行数值仿真,该直升机根据所建模型的要求在以尽可能短的时间击毁一艘导弹艇的同时与另一艘导弹艇保持最短距离,进而也能以最短时间迅速接近下一战区。仿真实例表明,文中的模型和方法可在一定程度上为实时作战指挥系统的研制、开发提供技术支持及理论依据。

This paper studies modeling of the pursuit and evasion resistance problem between a carrier helicopter and patrol torpedo boats, the aim of this model is to guide with minimum - time the helicopter to the war zone where there are patrol torpedo boats. Based on the theory of differential game and the idea of local optimization, this paper establishes a mathematical model and deduces the optimal controlling strategies for multi -sides and then the approach of this model＇s implementation is given. Finally, the resistance between a helicopter and two patrol torpedo boats is simulated; the helicopter destroys one patrol torpedo boat and keeps the shortest distance with the other one simultaneously, so it can approach the next war zone with minimum - tine. The simulation indicates that the model and the method may provide technical support and theoretical basis for research and development of live combat command system to a certain extent.
