RU 6, 2012 Formation of powerful nanosecond impulses by means of high-frequency generators of continuous action V. I. Kaganov Moscow State Tecnical University of Radio Engineering, Electronics and Automation (MIREA) 78 Vernadsky av., Moscow, 119454, Russia E-mail: Kaganovwil@yandex.ru The way of formation of periodic sequence of nanosecond impulses by transformation of energy of the continuous high-frequency fluctuations extending on the coaxial line is considered. <...> This method is similar to synchronization of fashions of the laser in an optical range. <...> Computer modeling of an offered way is carried out and the possible scheme of its technical realization is considered. <...> Рассмотрен способ формирования периодической последовательности наносекундных импульсов путем преобразования энергии непрерывных высокочастотных колебаний, распространяющихся но коаксиальной линии. <...>
