摘　　要：论述了基于D-S证据理论的多传感器数据融合方法。通常在强冲突情形下证据组合规则的组合结果是不符合常理的,其不同证据源的冲突处理成为数据融合的主要问题之一,文中提出了一种解决证据冲突情况下的近似算法。仿真结果表明该方法是有效的和可行的。This paper analyzes the data fusion method based on the D-S evidence theory.Dempster s combination operator is a poor solution for the management of the conflict among the various information sources at the normalization step.Conflict man- agement is a major problem especially during the fusion of various information sources.In this paper,a new approximation algo- rithm is proposed to combine conflicting evidence.The efficiency and feasibility of this method are validated through computer sim- ulatied resul...
