基于加权证据组合的多传感器目标识别

为了解决多传感器信息融合中不同等级重要信息源数据的融合问题,在证据理论基本概念的基础上,引入证据权的概念。依据证据权的不同对各条证据进行转化,使之可以用传统的方法进行证据合成。将这种方法应用到等级不同的多传感器目标识别中可以解决传统证据理论只能进行等级相同传感器目标识别的难题。识别实例表明,该方法提高了目标识别的准确性和有效性。

Multisensor target recognition based on the weighted evidence combination

For solving data fusion problem of inequably important information source in multi-sensor information fusion the concept of evidence weight is introduced based on basical concept of evidence weight. For transformation of each evidence according to its weight difference the evidence synthesis is completed using tradition method. In multi-sensor target recognition of different grade using this method the problem of target recognition of only same grade sensor using tradition evidence theory can be solved. An identification example using this method indicates that the precision and effectiveness of target recognition are raised.
