Study of Target Integrated Identification Based on Weighting

Considering weight of information source has an important effect on identification result in a target integrated identification system based on evidence theory,the paper proposes a target integrated identification technique based on weight,summarizes several methods of ascertaining subjective weight and objective weight,provides a formula of combined weight,and validates the improvement effect of evidence weighting idea based on D-S evidence theory.The study indicates that computing the weight of information source is necessary which can reduce the conflict of source and guarantee the validity and robustness of combination result.
