This paper studys the terrain following for low penetration aircraft ,and establishes the model of ALCM's clobber probability 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 .

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。

The computation of posterior probability considers the evidence E certain without dealing with uncertain evidence,in terms of this,the posterior probability is split the difference according to the probability of evidence appearing in Bayesian network and its extension network of Credal network,and is expressed by Credal set so as to provide the base of decision-making for decision-maker.

任何变量的后验概率计算都假定证据变量E是确定的，无法处理不确定证据下的后验概率。针对这个问题，提出在贝叶斯网络及其扩展的Credal网络中应用证据出现的概率对后验概率进行折中处理，并用不确定的Credal集表达其结果，从一定程度上为决策人员提供有意义的决策依据。

From the probabilistic equation of debris-flow occurrence, the curves of probability-slope-water level were obtained. One can see the influences of water level and sediment-layer slope on the probability of occurrence from the curves. The influence of coefficients of variation on occurrence probability are also shown in this paper.
