基于自相关方法的弱信息提取算法的研究

Abstraction of the Weak Information in the γ Ray Spectrum Based on Auto-correlation Method

在对γ能谱进行分析的基础上,介绍了γ能谱中对弱峰的处理与提取方法。论文采用自相关方法作为增强弱峰的方法,并且采用相应的分析方法,确定了弱峰的信息,然后采用小波软阈值滤波器对谱线进行处理。实验结果表明,自相关方法方便简单,能有效地对谱线中的弱峰信息进行定量与定性进行分析。

Based on the analysis of the gamma - ray spectrometry, the paper introduces the method to abstract the information about the weak energy peaks. The method adopts the autocorrelation to enhance the weak energy peaks to get their information. The soft threshold on wavelet transform is used to de - noise the synthetic spectrum. The results show that the Autocorrelation is effective to enhance the information of weak peaks.
