In order to improve the penetration and survival performance of hypersonic vehicles in the unpowered glide section under incomplete guidance and detection information or interference of detection equipment, this paper establishes a dynamic model of hypersonic vehicles in the glide section. The trajectory is optimized using sequential convex optimization method, which has better control energy consumption while satisfying terminal constraints, as well as ensuring terminal acceleration convergence and good computational performance. The trajectory tracking part adopts a linear LQR controller design to stably track and plan the trajectory. Compared with the traditional optimal control gui-dance law with angle constraints, the sliding phase adopts a trajectory planning-trajectory tracking method without the need for line of sight angle information. The relative angle information of the target can be introduced after the sliding phase ends, which has stronger survival performance in complex electromagnetic situations
