“…At the same time, it is very likely that the temperature of the outer surface will be below the dew point for a certain range of ambient temperature and humidity, which will inevitably lead to the precipitation of water condensate, which is extremely undesirable due to the significant absorption of water waves in the range of 0.1 -1 THz. The presence of an infrared filter [63] between the cold receiver input and the window significantly improves the picture. The infrared filter, which is a layered or loose structure fixed on the radiation screen of the cryostat, absorbs most of the radiation from the heated environment lying outside the band of received signals.…”

: The article presents a brief review of cooling systems of various temperature levels (from 0.1 K to 230 K) for radio astronomical receivers of photonics and electronics. The features of various levels of cooling and the requirements for the design of the cooling system are considered in detail, as well as approaches to designing interfaces for cooled receivers: vacuum, cryogenic, electrical, mechanical, optical, and others required for the effective operation of the receiver,. The presented approaches to design are illustrated by a series of joint developments of the authors carried out over the past 45 years, including those produced last year.

Представлен результат расчета пороговой освещенности наземной оптико-электронной системы (ОЭС) в видимом диапазоне в интервале 0,45–0,85 мкм. Разработана методика и выполнен расчет освещенности входного зрачка ОЭС от сигнала космического объекта (КО) сферической формы, подсвеченного Солнцем, в ночное время суток. Построена зависимость отношения сигнал-шум от дальности от Земли до КО.
