Abstract: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.
