Abstract: Изобретение относится к области гидроакустики, а именно к способам и устройствам обнаружения морских целей по их шумоизлучению, а точнее к способам определения координат целей с использованием интерференционных максимумов в автокорреляционной функции шума цели. Технический результат - повышение точности определения координат шумящей цели. Указанный технический результат достигается путем определения максимально компактной области возможного местоположения цели в пространстве «дистанция - глубина», в которой ищется такое положение источника сигнала по дистанции и глубине, для которого рассчитанные по лучевой программе интерференционные максимумы в АКФ широкополосного шума цели наилучшим образом совпадают с интерференционными максимумами в АКФ, измеренной на выходе антенны. 7 ил.

Granted: 2020-08-17
Abstract: FIELD: optical communication technique.SUBSTANCE: invention relates to optical communication and can be used in designing equipment for high-speed soliton transmission systems. Optical signal multiplexer using Kerr effect is made in form of four input polarization filters, after which optical beams acquire polarization and is exposed to electric field in electrooptical anisotropic substance with double refraction to change wave polarization. Further, the optical beam is transmitted simultaneously to output polarization filters, in which the polarization vector is orthogonal relative to the polarization vector of the input polarization filter. When the switching electric potential is applied, the polarization vector of the optical beam can be rejected. As a result, the beam can pass through only one output polarization filter.EFFECT: reliable direction with high speed of one of the input light fluxes into the output channel due to switching devices which change the polarization plane under action of the Kerr effect.1 cl, 1 dwg

Granted: 2021-02-10
Abstract: Предложенная паропроизводящая установка двухконтурного ядерного реактора с системой продувки и дренажа реализована по замкнутому контуру без классических расширителей продувки и рассчитана на максимальное давление рабочей среды в парогенераторах (ПГ). Продувочная вода ПГ объединяется в одну линию, охлаждается в регенеративном теплообменнике, затем в доохладителе продувки и дренажа и выводится за герметичную оболочку. За пределами герметичной оболочки продувочная вода ПГ подается на очистку в систему спецводоочистки продувочной воды ПГ, рассчитанную на максимальное давление рабочей среды в ПГ. После очистки продувочная вода возвращается в герметичную оболочку и через регенеративный теплообменник в питательные трубопроводы каждого ПГ. Достигаемым техническим результатом является увеличение расхода продувки ПГ, что приводит к ускоренной нормализация водно-химического режима даже при значительных отклонениях и, как следствие, к увеличению срока службы каждого ПГ и паропроизводящей установки в целом, а также снижение энергетических потерь на возврат очищенной продувочной воды во второй контур, при одновременной автономности системы из-за отсутствия связи с оборудованием машинного зала. 2 з.п. ф-лы, 1 ил.
