摘　　要：针对固体动力战术导弹的速度不可控、难以实现多约束协同制导的现状,采用领弹-从弹结构,提出了一种新型协同制导律以解决大机动目标的协同打击问题,旨在实现红外制导导弹在角度约束下的时间协同。该制导律在增广比例导引(APNG)的基础上,为领弹与从弹设计了考虑目标机动的角度约束偏置项,利用对剩余攻击时间的迭代估计为从弹设计了考虑目标机动的攻击时间协同偏置项。仿真结果验证了该制导律的有效性和可行性,并可为未来利用现有固体动力战术导弹实现协同作战提供参考。Aiming at the situation that the velocity can not be controlled and cooperative guidance with multiple constraints is difficult to be achieved by most of tactical missiles using solid rocket motor(SRM),a new cooperative guidance law based on leader-follower structure is proposed in order to solve the problem of coordination attack against high maneuvering targets.The law is proposed to achieve the coordination of impact time for infrared guided missile with impact angle constraint.Based on the augmented proportional navigation guidance(APNG),a bias term to satisfy impact angle constraint considering target maneuvering is designed for the leader missile and follower missile.By using iterative prediction for time to go,a bias term to achieve impact time coordination considering target maneuvering is designed for the follower missile.The simulation results verify the effectiveness and feasibility of the proposed method,which can give reference to achieve cooperative combat with available tactical missiles using SRM in future.
