Methodology for Creating a Reference Reflection Spectra Database for Space Objects Monitoring

The analysis of the influence of identical materials simultaneously stored in a special database on the accuracy of quantitative interpretation of reflection spectra in the framework of monitoring space objects is carried out. It is proposed to use a new classification of the reflection spectra of materials and coatings (according to the cross-correlation coefficient) and leave one material in each class of the generated database. The dependence of the identification performance on the threshold value of the correlation coefficient is shown.
