摘　　要：文中研究飞行器低空突防的地形跟随问题,基于布特沃斯地形模型,建立了飞行器撞地概率仿真模型,在各典型巡航条件下进行了大量的撞地概率仿真计算,并对仿真结果进行了深入地统计分析和研究,在此基础上,设计了相应的控制系统并确定了合理的控制参数,对飞行器地形跟随进行了飞行仿真。仿真结果证明了该模型的正确性和有效性。This paper studys the terrain following for low penetration aircraft ,and establishes the model of ALCM＇s clobber proba＇bility based on the Butterworth terrain model . It simulates much of the computation of its clobber probability under typical cruise conditions and analyzes those simulation results deeply. The control system is designed based on the lobber probability simulation result, and the reasonable control data are given. According to those research,the digital terrain following simulations are given. The simulation results proved that the model is reasonable and effective, and will provide theory-bases on helping the design and making use of the aircraft.
