The purpose of this paper is to describe one program of the National Academy of Sciences’ Committee on Radio Frequencies (“CORF”). This program uses legal means to protect radio astronomy frequencies from radio interference.CORF is composed of eminent scientists from the fields of radio astronomy, space research, remote sensing, meteorology, and wildlife tracking who use radio frequencies in conducting their research. CORF’s primary objective is to limit the level of harmful man-made interference in the bands used by these scientists as much as possible.

February 27 marks the 70th anniversary of the famous scientist in the field of radio astronomy and astrophysics, laureate of the State Prize of Ukraine in Science and Technology (2018), laureate of the USSR State Prize (1988), Honored Worker of Science and Technology of Ukraine (2001), laureate of the NAS of Ukraine Prizes named after S.Ya. Braude (2008) and M.K. Yangel (2013), Head of the Department of Low-Frequency Radio Astronomy, Deputy Director of the Radio Astronomical Institute of the NAS of Ukraine (since 2007), Doctor of Physics and Mathematics (1984), Academician of the NAS of Ukraine (2003) Olexander O. Konovalenko. Taking the opportunity, the editorial board of the Visnyk of the National Academy of Sciences of Ukraine interviewed Academician O.O. Konovalenko and asked about his path in science, his greatest achievements and plans for the future.

Galactic Background

Until recently, regular interferometric measurements were not performed at decameter wavelengths. The reasons are well known, i.e., effects of the ionosphere and the interplanetary plasma, the inherently high level of interference and of the galactic background, and the necessity to have very large antennas. Yet, because of the considerable interest in such observations, the Ukrainian SSR Academy of Sciences has started a project aimed at the development and construction of a system of decameter band interferometers (project URAN, from the “Ukrainian Radio Interferometers of Academy of Sciences (Nauk)”). By 1989, the system will involve four interferometers with baseline lengths between 40 and 900 km. The basic instrument of all these is the N–S arm of the large UTR-2 radio telescope operated by the Institute of Radio Astronomy in Kharkov. The antenna is an electrically controlled phased array of broad band dipoles (total length about 1800 m). At the other sites, the antennas are smaller phased arrays (maximum length about 230 m) consisting of crossed dipoles.
