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

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.
