The Method of Increasing Velocity Along its Original Velocity Direction by the Impulse Firing for the Ballistic Missile to penetrate the Anti-missile System in the Passive Ballistic Curve

The ballistic missile is easily intercepted by enemy because it moves along the fixed trajectory,and it is important for us to develop anti-defense.According to the characteristic of flying of the ballistic missile,this paper presents a method that a ballistic missile penetrates the anti-missile system,which is based on the increasing velocity along its original velocity direction by the impulse firing.The constraint equations of restricted the impulse firing are found and the method of solving it is described.The trajectory designed by the method consists of several ellipse curves,which is different from the classical trajectory and the trajectory of the missile maneuvers designed by other method.Two examples of the numerical stimulation are given,the results show that the trajectory of the missile maneuvers designed by the method can improved the capacity to penetrate the anti-missile system,which implies the method in this paper is feasible.
