基于均值向量检验法的模板比较算法

模板比较算法是核弹头及其核部件模板识别技术的一项关键技术.文中介绍了一种基于均值向量检验法的高分辨γ能谱指纹模板比较算法，并用放射源对其进行了有效性检验.检验结果表明，该算法是有效的，能够准确识别不同强度、不同组成的辐射源.研究还就模板构型的设计提出了两条建议. 关键词： 模板比较算法 模板识别技术 能谱指纹 均值向量检验法

Template match algorithm based on mean vector test

Template match arithmetic（TMA） is vital to the template identification technology of nuclear warheads and components. This paper introduces a TMA of high-resolution gamma-ray spectral fingerprint based on mean vector test. Some trials on gamma-ray samples were conducted to check the validity of TMA. The validity of TMA was comfirmed by correctly distinguishing between samples of different intensities and components. Two pieces of advice are given on the design of template structure.
