摘　　要：文中将数字地图和惯性导航系统相结合设计了一种无源自动地形跟随(TF)系统,给出了用数字地图描述地形轮廓的方法.阐述了地形参考导航定位的原理,在规划好理想地形跟随轨迹的基础上推导了地形跟随(TF)控制指令的计算方法,设计了 TF 飞行控制律。该系统从根本上消除了飞机低空突防时由于发射电磁波而暴露的可能性。This paper have designed a kind of passive automatic terrain following(TF)system combining digital map and inertia navigation system,have given the method that describes terrain outline with digital map,and has elaborated the principle of terrain reference navigation location.The calculaton method of terrain following(TF)control instruc- tion has been deduced on the basis of having planned the ideal terrain following route,and TF flight control law have been designed in writting.This system can eliminate the possibility radically that airplane is exposed because of project- ing electromagnetism wave when airplane low altitude penetration.
