“…Atmospheric transparency research is important not only for radio astronomy but also for telecommunications and radars. Millimeter-wave communication channels can provide the highest throughput (e.g., [16][17][18][19][20][21][22]) but are strongly affected by the atmosphere. Millimeter-wave radars are promising facilities for monitoring space debris and dangerous asteroids (e.g., [23][24][25][26]).…”

Radio astronomical observations at millimeter and submillimeter wavelengths are a very important tool of astrophysical research. However, there is a huge area in the northern Eurasia, including the whole Russian territory, which lacks sufficiently large radio telescopes effectively operating at these wavelengths. In this review we describe our long-term efforts to find suitable sites for such radio telescopes in this area, that is, sites with good atmospheric transparency at millimeter and submillimeter waves. We describe methods and instruments used for measurements and evaluations of the atmospheric opacity. They include special radiometric systems, which are used for estimations of the atmospheric opacity from the sky brightness measurements. Evaluation of the precipitable water vapor from such measurements by the artificial neural network is discussed. Alternative approaches use global atmospheric models and signals of the Global Navigation Satellite Systems. To date, a long-term radiometric monitoring has been performed at several candidate sites and atmospheric conditions for many sites have been evaluated using global atmospheric models. Several sites with the best atmospheric transparency at millimeter and submillimeter wavelengths have been selected. They can be effectively used for astronomical observations at least in the major atmospheric transparency windows at 1.3 mm and 0.85 mm. These results can be also used for space communications and radar systems.

“…Experiment was carried out based on 1 kW/0.263 THz tube and lineаr dependence between the control (anode) voltage and the output frequency was observed. As a result, high quality transmission of sound and pseudo random bit sequence (with a speed up to 1.5 Mbit/s) has been obtained [35].…”
