Аннотация
The paper proposes a new method for the frequency shift determination of the spectrum obtained under conditions of low resolution of the analyzer, which allows, due to mathematical processing of the signal describing the spectrum, to determine its frequency shift with a resolution two orders of magnitude greater than the instrumental one. The method is based on representing a signal describing a frequency-shifted spectrum as a continuous function differentiable everywhere, expanding it into a Taylor series, approximating its derivatives by finite differences of a given order, and determining the frequency shift by the least squares method. The mathematical substantiation of the method as well as the results of numerical experiments are given. The prospects for the application of the proposed method are discussed.
