基于加权的目标综合识别技术

在基于证据理论的目标综合识别系统中,综合考虑信息源权重对识别结果有重要的影响.提出了基于加权的目标综合识别技术,总结了几种常用的主观权重和客观权重获取方法,给出了组合权重的计算公式,针对D-S证据理论仿真验证了基于证据加权思想对合成结果的改进效果.研究表明,在进行目标综合识别时考虑信息源的权重是必要的,它能有效化解信源冲突,保证合成结果的合理性和稳健性.

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.
