Модельные эксперименты проведены с использованием данных Геологической службы США и лабораторных проб. Показано, что предложенный метод может улучшить несмешивание разреженных спектров и быть полезен для других приложений спектрального анализа.</p></abstract><trans-abstract xml:lang="en"><p>A novel extraction and purification method for identifying pure materials in space targets is presented in this paper. Simulation experiments are carried out using data from the United States Geological Survey and laboratory sample material. Experimental results show that the proposed method can successfully improve the unmixing of sparse spectra. This algorithm should also be suitable for other spectral analysis applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектральная информация</kwd><kwd>чистое вещество</kwd><kwd>спектральное несмешивание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spectral Information</kwd><kwd>pure material</kwd><kwd>spectral unmixing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">This work is supported by the National Natural Science Foundation of China (Grant No. 61575015).</funding-statement><funding-statement xml:lang="en">This work is supported by the National Natural Science Foundation of China (Grant No. 61575015).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">S.
