The pitch-up trajectory is a high parabolic trajectory. Long range interceptor missiles will be important for future air defense. Research indicates that a high parabolic trajectory can enhance the missile range. A method of generating high parabolic trajectories based on a virtual target guidance law is proposed in this paper. The proposed method is formulated and its effectiveness is demonstrated by two test simulations. The simulation results show that a missile can fly in a high parabolic trajectory with good characteristics using the virtual target guidance law. The proposed method fulfills the current needs and is suited for engineering applications.
