Получены аналитические выражения для доверительных вероятностей, соответствующих заданным временным интервалам. Анализируются зависимости доверительных вероятностей от отношений "сигнал/шум" при приеме сигналов со случайными амплитудами и начальными фазами.</p></abstract><trans-abstract xml:lang="en"><p>The article considers statistical descriptions of time interval estimation for air target motion trajectory au-tomatic detection in radar information secondary processing. Analytical expressions for confidential proba-bilities of the air target motion trajectory automatic detection are obtained. It is supposed that the target loca-tion mark appearance is invariable within the whole observation time. The confidential probability dependences are analyzed from the signal noise ratio for the received signals with random amplitudes and elementary phases. It is shown that the target motion trajectory determination probability increases with the increase of signal noise ratio and decrease of radar observation period number.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Автозахват траектории</kwd><kwd>среднее время автозахвата</kwd><kwd>дисперсия</kwd><kwd>доверительная вероятность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Trajectory Auto Capture</kwd><kwd>Average Time of Auto Capture</kwd><kwd>Dispersion</kwd><kwd>Confidential Probability</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">Радиотехнические системы: учеб. для студентов вузов / под ред.
