ABSTRACT Natural environment consists of terrain, ocean, atmosphere and space, it has important effects on the performanceof military systems. Synthetic natural environment (SNE) is the representation of natural environment in MS systems. The research on SNE in the world is surveyed, the key technologies of MS of SNE are discussed, a prototype SNE simulation System for CGF application is designed, and then a development process of SNE system is presented from the implementation prospective. Finally, a briefly introduction to the application of this prototype SNE simulation System in the X-type cruise missile simulation system is made.
