为了更好地辅助决策人员进行空袭目标选择，首先分析了影响空袭目标选择的因素；利用Netica软件得到训练样本集；利用ID3算法构造决策树模型，并从中挖掘出空袭目标选择的14条规则；最后总结出目标选择遵循的6条指导原则。仿真结果表明，利用决策树进行空袭目标数据挖掘，准确率比较满意，是一种目标选择的新思路。

The purpose of this article is to help the decision-makers select the air attack targets.Firstthe factors that have effect on air attack target selection were analyzed.ThenNetica software was used for obtaining the training sample setand the decision tree model was constructed by ID3 algorithm. Finally14 rules and 6 guiding principles were obtained for the target selection.From the simulation resultsit can be concluded that the accuracy of the decision tree model is satisfactorywhich is a new idea for target selection.
