高超声速飞行器预警资源分配方法

Early Warning System Resource Allocation Method for Hypersonic Vehicles

针对高超声速飞行器跳跃滑翔过程中预警系统资源分配问题,提出了一种基于隐马尔可夫模型的预警资源分配方法。首先分析高超声速飞行器跳跃滑翔的运动特性,建立了目标运动状态的马尔可夫状态转移模型;然后将马尔可夫模型应用到资源分配中,提出了基于隐马尔可夫模型的资源分配方法;在资源分配过程中,基于信息熵的概念,将单位资源消耗产生的信息增益作为资源分配的目标函数。最后通过仿真分析,验证所提分配方法的有效性和可行性。仿真结果表明:该方法在保证跟踪精度的前提下能够对预警资源进行合理的分配。

In order to solve the problem of resource allocation in early warning system during jump gliding of hypersonic vehicles,an early warning resource allocation method based on hidden Markov model was proposed.The motion characteristics of jump gliding were analyzed,the Markov state transition model of target motion state was established,and then the Markov model was applied to resource allocation,and a resource allocation method based on hidden Markov model was proposed.In the process of resource allocation,based on the concept of information entropy,the information gain generated by unit resource consumption was regarded as the objective function of resource allocation.The effectiveness and feasibility of the resource allocation method were verified by simulation analysis.The simulation results show that the method can make reasonable use of the early warning resources on the premise of ensuring the tracking accuracy.
