Distributed multi-sensor fusion for target recognition using weighted D-S evidence theory
基于加权D-S证据理论的分布式多传感器目标识别

Dempster-Shafer(D-S) evidence theory has been widely used in data fusion systems.A method based on the weighted D-S evidence theory was proposed for target recognition in the distributed multi-sensor system.First,the analysis of the system's formation model showed that the decision credibility of a sensor was jointly determined by two elements,namely the degree of support and the distance between it and the target.As the decision credibility can be presented by the corresponding weight of the weighted D-S evidence theory,it was obtained by a formula based on the two elements.Finally,the encouraging experimental results demonstrate the effectiveness of the method.
