Предложена методика последовательного распознавания радиолокационных объектов, основанная на совместном применении метода опорных векторов и последовательного критерия отношения вероятностей Вальда. На этапе обучения формируется разделяющая гиперплоскость, относительно которой многомерное признаковое пространство преобразуется в одномерную решающую величину – ориентированное расстояние до границы разделения классов. По обучающей выборке оцениваются условные вероятности правильного и ложного распознавания, используемые для формирования приращений решающей статистики. На этапе распознавания статистика рекуррентно накапливается и сравнивается с пороговыми уровнями до принятия решения. Методика сохраняет единую алгоритмическую структуру при изменении состава признаков и допускает адаптацию путем повторного обучения классификатора.</p></abstract><trans-abstract xml:lang="en"><p>The article considers the synthesis of a binary radar recognition device in the absence of a priori analytical models of classification feature distributions. A methodology for sequential radar target recognition is proposed, based on the combined use of support vector machines and Wald’s sequential probability ratio test. At the training stage, a separating hyperplane is constructed, with respect to which the multidimensional feature space is transformed into a one-dimensional decision variable represented by the signed distance to the class-separation boundary. Based on the training sample, the conditional probabilities of correct and false recognition are estimated and used to form increments of the decision statistic. At the recognition stage, the statistic is recursively accumulated and compared with threshold levels until a decision is made. The methodology preserves a unified algorithmic structure when the feature set changes and allows adaptation through repeated classifier training.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиолокационное распознавание</kwd><kwd>двухальтернативная классификация</kwd><kwd>последовательный критерий отношения вероятностей</kwd><kwd>метод опорных векторов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radar recognition</kwd><kwd>binary classification</kwd><kwd>sequential probability ratio test</kwd><kwd>support vector machines</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">Fu K.
