拦截机动目标的三维协同中末一体化制导律

针对空中来袭目标机动能力较大，单枚导弹无法有效拦截的问题，提出了拦截机动目标的三维协同中-末一体化制导律。根据目标和拦截弹的最大机动能力计算所需的最少拦截弹数量，解算出末制导的初始阵位约束，根据阵位约束，设计基于改进比例导引的协同末制导律。基于中制导开始时目标速度，迭代求解出预测命中点以及中末交班约束，提出基于预测命中点的时间角度协同中制导律。在三维场景下对协同中末制导律进行仿真验证，结果表明：该方法能够有效满足中末交班的阵位要求以及末段拦截精度，实现对机动目标的有效拦截。

Three - Dimensional Cooperative Mid-Terminal Guidance Law for Intercepting Maneuvering Targets

Aiming at the problem that a single missile cannot intercept the incoming target effectively due to its large maneuvering ability, a three-dimensional cooperative mid-terminal guidance law for intercepting maneuvering target is proposed. The minimum number of interceptors is calculated according to the maximum maneuvering ability of target and interceptor, and the initial array constraint of terminal guidance is calculated. According to the array constraint, the cooperative terminal guidance law based on improved proportional guidance is designed. Based on the target velocity at the beginning of middle guidance, the predicted hit point and middle and end shift constraints are solved iteratively, and the time angle cooperative middle guidance law based on the predicted hit point is proposed. The simulation results show that the proposed method can effectively meet the array position re-quirements and terminal interception accuracy of the middle and terminal shift, and effectively intercept maneuvering targets.
