This paper discusses the adaptive angle method of the terrain following in the very low altitude penetration flight. The paper includes the following parts: (l)Introduce the development and the application of the terrain following technique. (2)Discuss the principle of the adaptive angle method and the way of generating control instruction. (3)Compare the two classical methods of terrain following-adaptive angle method and templet method. (4)Discuss the model of the optimal terrain following flight path and the method of adjusting the control parameters of adaptive angle method. (5)Analyze the basic requirement and quality of terrain following system, and give a typical flight control system for terrain following. (6)Simulate the terrain following system.
