| Abstract: | A noise reducing method based on multivariate statistical analysis for gamma-ray spectra-the NASVD method(Noise Adjusted Singular Value Decomposition),main idea and algorithm for realizing of the NASVD are introduced in the paper. The NASVD method is used to an airborne gamma-ray data set, the result has shown that the method can dramatically remove statistical noise from raw gamma-ray spectra and the quality of processed data is much better than that of the conventional spectral denoising methods. |
