This explains long standing interest in building a low frequency radio telescope on the farside of the Moon. Experience from ground-based observations near the ionospheric cutoff in dealing with the interference, ionosphere, and wide-field imaging/dynamic range problems provides crucial information for future radioastronomic experiments on the Moon. In this purpose we observed non-intensive solar bursts on the example of solar drift pairs (DP) ","authors_text":"A.A. Konovalenko, A.A. Stanislavsky, A.I. Brazhenko, A.V. Frantsuzenko, H.O.
