摘要
A method is proposed for estimating the parameters used in the deconvolution technique. The proposed method is based on the use of the Fourier transform modulus of the spectrum being treated with the purpose of obtaining information about the characteristics of the spectral bands and random measurement errors. Formulas are given that permit estimation of the values of noise variance in the experimental spectrum, the low-pass filter passband, and the contour half-width of the high-pass filter. Results are considered for the application of the proposed formulas for determining the parameters used with the deconvolution of synthetic and experimental spectra. It has been concluded that practical use of the proposed method of a priori estimation of the parameters permits, to a certain extent, the optimization of the process of deconvolution of spectral curves.
