导弹摆脱距离可控的最优突防制导律

Aiming at the problem of maneuver penetration in the terminal guidance section of the attack missile in three-dimensional space, a penetration guidance law with controllable the minimum distance between the attacker and the defender ( escape distance) is proposed based on the optimal control theory. A system of relative equations of motion between an attacker, a target, and a defender is established. Assuming that the defender adopts the proportional guidance law, introducing the zero-effort-miss distance, and considering the problem of controllable escape distance and minimum control energy of the attacker, the optimal penetration control model is derived and solved based on the optimal control theory. Based on the BP neural network, an agent model reflecting the nonlinear relationship between the states of the offensive and defensive sides of the current battlefield, the key parameter of the guidance law and the escape distance is established, and the setting method of the key parameter in the penetration guidance law is given. The simulation results show that by using the method of this paper, the control of the escape distance during the penetration of the attacker can be achieved in three-dimensional space under the premise of saving as much energy as possible.
