【摘要】 为解决高速滑翔飞行器难以实现高精度跟踪的问题,提出了一种针对临近空间高速跳跃滑翔式机动目标的跟踪算法,其核心是在正弦波(sine wave,SW)自相关模型的基础上,将有向图切换原理与交互式多模型算法结合,从而实现模型集的自适应以覆盖周期机动角速度的变化,并利用容积卡尔曼滤波方法进行滤波器的设计。通过仿真试验将SW单模型和SW交互式多模型进行比较,验证了有向图切换交互式多模型算法在跟踪临近空间高马赫数跳跃滑翔式机动目标时的优越性和模型集切换的有效性。更多还原

【Abstract】 In order to achieve high-precision tracking of high-speed glide vehicle, a tracking algorithm for hypersonic jump-gliding maneuvering targets in the near space is proposed. Its core is based on the SW(Sine Wave) model, which combines the digraph switching principle with the interactive multi-model algorithm to achieve the adaptation of the model set. In order to cover the change of the periodic maneuvering angular velocity, the cubature Kalman filtering method is used to design the filter. The simulation experiment is compared with SW single model and SW interactive multi-model to verify the superiority of the proposed algorithm when tracking the hypersonic jump-gliding maneuvering target in near space and the effectiveness of model set switching.更多还原
