Biography:
He was born on July 18, 1932.
Since 1956 he has been an employee of the Department of Radio Astronomy of the Crimean Astrophysical Observatory.
In 1963 he graduated from the All-Union Correspondence Energy Institute with a degree in radio engineering.
In 1974 he defended his dissertation on the topic: "The results of the study of the components of the Sun in the millimeter range of radio waves, which is slowly changing".
He died on June 16, 1983 in the Katsiveli village.
The main scientific works relate to the fields of solar physics and astrophysics. In the 1970s, he conducted centimeter and millimeter radio astronomical studies on the RT-22.
In 1969 and 1971 he took part in the first intercontinental RSDB experiments based on Simeiz - Green Bank. In 1971 he went on a research trip to the United States to process the RDB data, as well as to conduct research on the Sun on radio telescopes of the National Radio Astronomical Observatory. He developed and created the basic hardware of the 22-meter RT-22 radio telescope - a set of radio astronomical equipment in the range of 4-16 mm to study the structure and basic physical properties of active regions in the Sun. The scheme of a multi-channel 8 mm radiometer was implemented, which with the help of RT-22 allowed to record radio radiation simultaneously from five different parts of the active region on the Sun - the scheme of a radio telescope with a fan pattern. It is shown that all sources of increased radio radiation in the range of 1.35-4 mm are optically dense formations, which radiation is thermal. The close connection of the sources of the S-component at a wavelength of 8 mm with the hills of the magnetic field at the level of the photosphere in areas without groups of spots was revealed. It is shown that the direction of rotation of the polarization vector in the sources corresponds to the output of an unusual wave. Based on the study of the results of observations during the passage of Mercury to the Sun's disk, data on the fine structure of the Sun at a wavelength of 8 mm were obtained. Two types of inhomogeneities with characteristic sizes from 1.6 "to 3.4" and from 17 "to 40" were identified.
