Abstract
Re-entry guidance is one of the primary tasks of a global strike mission. Hypersonic and common aero vehicles are currently being investigated for missions like this. This paper proposes a guidance law considering not only the constraints of terminal status and flight process, but also the avoidance of no-fly zones, to meet the requirements of a global strike mission. An improved A* algorithm is proposed first to achieve a real-time trajectory planning process. Then a dynamic optimization guidance law based on the model of a hypersonic vehicle considering single and multiple no-fly zones is founded. Numerical simulations show the robustness and rapidity of this optimization method.
