Выполнена оценка максимальной амплитуды возмущающего воздействия, при котором задача оценки неизвестной частоты может быть решена в рамках предлагаемого подхода. Задача оценки частоты решается в несколько этапов: параметризация исходного измеряемого сигнала к виду линейной регрессии; применение нелинейного преобразования координат исходной регрессионной модели; оценка неизвестной частоты. Результаты работы могут быть использованы при решении практических задач в областях обработки и оценивания параметров синусоидальных сигналов, подверженных влиянию возмущения.</p></abstract><trans-abstract xml:lang="en"><p>This paper proposes a new algorithm for estimating the carrier frequency of an amplitude modulated signal in the presence of measurement noise. An estimate is provided for the maximum amplitude of the disturbance for which the problem of estimating the unknown frequency can be solved using the proposed approach. The problem of frequency estimation is solved in several stages: parameterization of the initial measured signal to the form of linear regression; application of a nonlinear transformation of the coordinates of the initial regression model; estimation of the unknown frequency. The results of the paper can be used to solve practical problems in the areas of processing and evaluating sinusoidal signals subject to disturbances.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синусоидальный сигнал</kwd><kwd>линейная регрессионная модель</kwd><kwd>идентификация параметров</kwd><kwd>возмущение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sinusoidal signal</kwd><kwd>linear regression model</kwd><kwd>parameter identification</kwd><kwd>disturbance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hsu L., Ortega R., Damm G.
