基于贝叶斯网络的空中目标威胁估计方法研究

针对当前威胁估计中存在的问题，提出了基于贝叶斯网络的空中目标威胁估计方法。文章从威胁估计的概念出发，构建了基于贝叶斯网络的威胁估计功能框架，在对输入的防空作战事件进行分类定义的基础上，给出了事件关联在贝叶斯网络中的实现方法，同时对模型的建立步骤进行了说明。文中提出的威胁估计方法在融合了目标威胁先验信息的基础上，通过战场观测到的不确定信息进行推理，其结果具有很强的可信性，相应的建模思路可为威胁估计系统的构建提供有益的参考。文章的最后以一个示例说明了方法的有效性。

Research on Threat Assessment to Aerial Target Based on Bayesian Network

Aimming at the present problems existing in threat assessment,a novel air defense oriented threat assessment method based on bayesian network is proposed in this paper.In the view of threat assessment's definition,a function framework which is based on bayseian network is built up.Meanwhile,by the classification definition of input air defense events,the corresponding implement approach of event correlation in bayesian network is presented,among which the modeling procedure is described in detail.By combing...
