  Earth-based observations are complicated by the opacity of Earth's ionosphere
at very low frequencies and strong man-made radio frequency interference. 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) at
decameter-meter wavelengths with large and small arrays as well as by a single
crossed active dipole. We used the large Ukrainian radio telescope UTR-2, the
URAN-2 array, a subarray of the Giant Ukrainian radio telescope (GURT) and a
single crossed active dipole to get the spectral properties of radio bursts at
the frequency range of 8-80 MHz during solar observations on July 12, 2017.
Statistical analysis of upper and lower frequencies, at which DPs are recorded,
shows that the occurrence of forward DPs is more preferable at lower
frequencies of the decameter range of observations in comparison with reverse
DPs generated more likely at meter wavelengths. We conclude that DPs can be
detected not only by antenna arrays, but even by a single crossed active
dipole. Thus the latter antenna has a good potential for future low-frequency
radio telescopes on the Moon.
