Спектральный анализ выполняется помехоустойчивым методом SFK. Апробация  проведена  на  синтетических  данных,  материалах  инженерной  сейсморазведки  Республики  Алтай  и данных  3D-сейсморазведки  нефтегазовых  месторождений  России.  Результаты  показали  устойчивое  выделение фундаментальной  моды  в  различных  геологических  условиях  и  возможность  полностью  автоматизированной обработки без перенастройки параметров.</p></abstract><trans-abstract xml:lang="en"><p>An adaptive automatic algorithm for surface-wave dispersion curve extraction AACPDC (Automatic Adaptive Clustering Picking Dispersion Curves) was developed for the MASW method. The algorithm combines spectralimage thresholding, DBSCAN clustering, curve reconstruction in low signal-to-noise ratio regions, and outlier correction. Spectral analysis is performed using the noise-resistant SFK method. The algorithm was validated on synthetic data, engineering seismic surveys from the Altai Republic, and 3D seismic data from Russian oil and gas fields. The results demonstrated robust extraction of the fundamental mode under various geological conditions and fully automated processing without parameter retuning.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сейсморазведка</kwd><kwd>поверхностные волны</kwd><kwd>спектральный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>seismic</kwd><kwd>surface waves</kwd><kwd>spectral analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке проекта ФНИ FWZZ-2026-0052.</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the project No. FWZZ-2026-0052.</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">Верхоланцев А.В.
