It is intended to use the mode of sequential obtaining of images at different
frequencies in order to study coronal magnetic fields, in addressing problems of
predicting solar activity, and in investigating low-contrast structures such as coronal
holes and filaments. Coronal mass ejections are commonly characterized by the
angular size as large as several tens of min of arc. Therefore, it is more appropriate to
investigate such phenomena in the mode of sequential obtaining full solar images at
different frequencies. Observations of ejections in the mode of simultaneous
obtaining a full solar image are appropriate only when accompanied by fast
occurring processes. For investigating the dynamics of solar activity (flares and,
possibly, coronal mass ejections), it is intended to use the mode of simultaneous
obtaining of a full solar image at 5.7 GHz  frequency and high spatial harmonics of
corresponding images at the other wavelengths. A tentative configuration of antennas
for this mode is illustrated in Fig. 6. The field of view for frequencies above 5.7 GHz
in this case will be reduced to a few min of arc. This should not have a substantial
influence on the observations of flares as a consequence of their small angular size.
However, in observations of coronal mass ejections, such a limitation could have a
serious influence.
     It should be noted that the question as to the selection of the antenna
configuration for simultaneous obtaining of images at different frequencies is open.
It seems most likely that it will be answered in the process of observations. For this it
is important that the whole instrument has a sufficient flexibility. Such a flexibility is
ensured by equipping each antenna with a controlled multiwave receiver and by the
control of the process of calculating cross-correlation functions of signals received
from antennas.
