Analysis method for lunar landers landing safety

In the lunar exploration program Ⅱ, the lunar lander to a safelanding site selection and realize safelanding is the key issues. Without considering engine control, attitude control and dynamic property, a high-definition landing territory was simulated on computer based on the low-definition data and known characteristic models of lunar surface. One times landing security can be obtained by computing and analyzing lander profiles and landing safety requirement. The landing safety possibility of this terrain can be obtained by computing many times landing only under the condition of same lander profiles. The landing territory, lander profile and safety parameters were simulated on computer by this method can be applied to both ground simulation experiments and real-timely analyzing possibility of landing safety during soft landing on the lunar surface.
