基于面向机动目标的协同攻击制导律

Attack Guidance Law Based the Maneuvering Target

针对机动目标协同攻击问题,要求制导系统具备对目标的跟踪能力,基于固定时间收敛控制理论设计机动目标制导律,在此基础上,改进目标跟踪模型,将扩张状态观测器与扩张卡尔曼滤波结合,并且采用传感器一致性融合算法,实现了目标跟踪能够适应多变化有噪声的场景,估计精度和速度均显著提升。进一步介绍针对机动目标提出的制导律和固定时间收敛扩张状态观测器。最后利用仿真实验验证了所设计协同制导律的有效性。

In this paper,in response to the problem of cooperative attacks against maneuvering targets,the guidance system is required to have the ability to track the targets and a maneuvering target guidance law is designed based on the fixed-time convergence control theory.On this basis,the targets tracking model is improved,the extended state observer is combined with extended Kalman filter and the multi-sensor consensus fusion algorithm is used to track the target that can adapt to multiple noisy scenes,and the estimation accuracy and speed are significantly improved.The guidance law and fixed-time convergent extended state observer for maneuvering targets are further introduced.Finally,simulations are performed to verify the effectiveness of the guidance laws.
