Biography:
He was born on July 31, 1921.
In 1953 he graduated from the Moscow Energy Institute with a degree in radio engineering and in the same year by distribution he was sent to the Crimean Astrophysical Observatory of the USSR Academy of Sciences to the position of junior non-researcher. He worked his way up to the head of the department.
In 1963 he defended his dissertation for the degree of Candidate of Physical and Mathematical Sciences at M. V. Lomonosov Moscow State University.
Together with Vvedensky V. A., Pogribny B. M., Semenov Y. M., Stezhka P. M. developed a modernized control system for a 22-meter radio telescope of millimeter waves in the Crimean Astrophysical Observatory of the then USSR Academy of Sciences on the basis of computers. In the automatic mode, which is the main, the drives of fast movement on the computer command perform the re-installation of the antenna during the transition from one object of observation to another and rough aiming of the antenna at the source. Slow motion devices perform accurate guidance and observation of the selected object, the motion of which is also set by the computer.
Together with Skulachev D. P., Nesterov M. S., Efanov S. V., Strukov I. A., Korogod V. Vю conducted observations in early 1986 on a wave of 8.2 mm 171 radio sources with a limit of about 0 , 1 Jan (3σ).
He died on October 16, 2008 in the Katsiveli urban village.
The main scientific works relate to the fields of astrophysics, solar physics. He is one of the founders of radio astronomy at the Crimean Astrophysical Observatory. With his participation in 1955 the first radio telescope of the meter wave range was made at the Crimean Astrophysical Observatory, on which regular observations of the Sun were started. In 1957 he headed the first radio astronomy group. To study the lower layers of the solar atmosphere in 1956 began to make a second radio telescope at 10 cm, test observations which began to be conducted in 1957. Radio astronomical methods of observation gave new, previously unknown, information about the upper layers of the solar atmosphere, limited availability. The next radio astronomical instrument of the Crimean Astrophysical Observatory in 1957 was a radio spectrograph operating in the range from 2 to 3 m. flashes. and with flares and other rapidly changing optical processes in the Sun.
He headed the Department of Radio Astronomy established at the Crimean Astrophysical Observatory since 1962. With his participation in 1966, the 22-meter RT-22 radio telescope was built and put into operation in Simeiz, one of the five best instruments in the world. Research has been launched:
a) the study of solar radiation in a wide range of waves up to millimeters,
b) observation of the variability of galactic and extragalactic sources of radio radiation,
c) measurement of ultrafine structure of compact sources of cosmic radio radiation by the method of radio interferometry with ultralong bases.
In 1969 he participated in the organization and conduct of the first intercontinental observations on RT-22 by radio interferometry with ultralong bases for the study of the size and ultrafine structure of cosmic radio sources. The experiment was successful, on the basis of Crimea-Hystek (USA) a record angular resolution of 0.0004 "was obtained.
In 1987 he was awarded the USSR State Prize for work in the field of radio engineering. He is the author of about 50 scientific papers.
