This article provides a comparative analysis of various methods for filtering a signal obtained using a spectroradiometer. The following filtering methods were used in the study: moving average method, spline interpolation method, and Savitsky-Golay method. An Ocean Insight SR-2XR250-25 spectroradiometer was used as a spectral radiation receiver, and a white LED was used as a radiation source. Based on the results of the study, the most optimal filter for processing the results of spectral measurements of light sources was determined, which will be further used in the software of the goniospectroradiometer being developed.

Keywords: spectral density of radiation, spectroradiometer, radiation receiver, radiation source, signal filtration methods
