Modified combination rule of D-S evidence theory

For solving information fusion problem of inequality important information in integrated target recognition the concept of evidence weight is introduced based on D-S reasoning. For transformation of each evidence according to its weight difference the evidence synthesis is completed using tradition method in integrated 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.
