Авторами принимается предположение о коррелированности траекторий, позволяющее экстраполировать значения координат с учетом их приращений за период сканирования. Процедура обнаружения состоит из двух этапов. На первом осуществляется обнаружение классическим пороговым методом с низким уровнем порога, обеспечивающим высокую вероятность правильного обнаружения при высоких значениях вероятности ложных тревог. При этом возникает неопределенность в выделении траектории объекта на фоне ложных траекторий. Из-за статистической независимости координат ложных траекторий по сравнению с коррелированными координатами объекта средняя длительность первых из них меньше средней длительности вторых. Это отличие используется для решения задачи обнаружения на втором этапе на основе метода временной селекции. Полученные результаты позволяют судить о степени выигрыша в вероятности обнаружения при использовании предлагаемого метода.</p></abstract><trans-abstract xml:lang="en"><p>To increase the efficiency of detecting moving objects in radiolocation, additional features are used, associated with the characteristics of trajectories. The authors assumed that trajectories are correlated, that allows extrapolation of the coordinate values taking into account their increments over the scanning period. The detection procedure consists of two stages. At the first, detection is carried out by the classical threshold method with a low threshold level, which provides a high probability of detection with high values of the probability of false alarms. At the same time uncertainty in the selection of object trajectory embedded in false trajectories arises. Due to the statistical independence of the coordinates of the false trajectories in comparison with the correlated coordinates of the object, the average duration of the first of them is less than the average duration of the second ones. This difference is used to solve the detection problem at the second stage based on the time-selection method. The obtained results allow estimation of the degree of gain in the probability of detection when using the proposed method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиолокационная станция</kwd><kwd>обнаружение</kwd><kwd>селекция траекторий</kwd><kwd>вероятность правильного обнаружения</kwd><kwd>вероятность ложных тревог</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radar station</kwd><kwd>detection</kwd><kwd>trajectory selection</kwd><kwd>probability of detection</kwd><kwd>probability of false alarms</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">Tihonov V.
