Рассмотрена задача оценки частоты несущей по измерениям амплитудно-модулированного сигнала в присутствии неизвестных ограниченных возмущений и изменяющейся огибающей. Существующие методы идентификации, основанные на регрессионных преобразованиях, как правило, требуют выполнения условия малости возмущений, что ограничивает их практическое применение. Научная новизна работы заключается в разработке робастного алгоритма оценки частоты несущей, который сохраняет регрессионную структуру параметризации сигнала на основе задержки и не требует предположения о малой величине возмущений. Метод. Предложенный метод основан на параметризации измеренного сигнала с использованием задержанных измерений, что позволяет свести задачу к линейной регрессионной модели. Для оценки неизвестного параметра применен адаптивный алгоритм с нелинейностью насыщения, ограничивающей влияние больших ошибок регрессии. После оценки регрессионного параметра выполняется восстановление частоты несущей. Основные результаты. Эффективность представленного метода проверена в численных экспериментах для амплитудно-модулированных сигналов в условиях шумов и импульсных возмущений. Проведено сравнение с нормализованным градиентным алгоритмом и методом степенного преобразования регрессии. Результаты моделирования показали более быстрое уменьшение ошибки оценки и более высокую устойчивость предложенного алгоритма. Обсуждение. Полученные результаты демонстрируют преимущество разработанного метода по сравнению с существующими алгоритмами оценки частоты в условиях сильных возмущений. Метод может быть применен в задачах обработки радиосигналов, системах связи и алгоритмах распознавания модуляции. Перспективными направлениями дальнейших исследований являются разработка дискретных реализаций алгоритма и его расширение на случай многокомпонентных сигналов. </p></abstract><trans-abstract xml:lang="en"><p>This paper considers the problem of carrier frequency estimation from measurements of an amplitude-modulated signal in the presence of unknown bounded disturbances and a time-varying envelope. Existing identification methods based on regression transformations usually require a small-disturbance condition, which limits their practical applicability. The scientific novelty of this work consists in the development of a robust carrier-frequency estimation algorithm that preserves the regression structure of delay-based signal parameterization and does not require the assumption of small disturbance magnitude. The proposed method is based on the parameterization of the measured signal using delayed measurements, which makes it possible to reduce the problem to a linear regression model. To estimate the unknown parameter, an adaptive algorithm with a saturation nonlinearity is used, limiting the influence of large regression errors. After estimating the regression parameter, the carrier frequency is reconstructed. The effectiveness of the proposed method is verified through numerical experiments for amplitude-modulated signals under noise and impulsive disturbances. A comparison with a normalized gradient algorithm and a power-transformed regression method is performed. The simulation results demonstrate a faster reduction of the estimation error and improved robustness of the proposed algorithm. The obtained results show the advantage of the proposed method over existing frequencyestimation algorithms under strong disturbances. The method can be applied to radio-signal processing, communication systems, and modulation-recognition algorithms. Future research directions include the development of discrete-time implementations of the algorithm and its extension to multi-component signals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>амплитудно-модулированный сигнал</kwd><kwd>оценка частоты несущей</kwd><kwd>параметризация с использованием задержек</kwd><kwd>нелинейное подавление возмущений</kwd><kwd>расширение динамического регрессора</kwd><kwd>робастная адаптивная идентификация</kwd><kwd>нелинейность насыщения</kwd><kwd>импульсный шум</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amplitude-modulated signal</kwd><kwd>carrier frequency estimation</kwd><kwd>delay parameterization</kwd><kwd>nonlinear disturbance attenuation</kwd><kwd>dynamic regressor extension</kwd><kwd>robust adaptive identification</kwd><kwd>saturation nonlinearity</kwd><kwd>impulsive noise</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (проект № 25-29-00896).
