The
radiotelescope RATAN-600 already more than two tens years is used for solar investigations. In
|
|
|
|
the
last several years ago the radiotelescope RATAN-600 (Fig.1) is used for
regular solar study in
|
|
|
|
monitoring
mode (Korolkov&Parijskij,1979; Parijskij, 1993, Bogod &Gel'freikh,
1998, .Bogod et al.,
|
|
|
|
1999).
The solar observations is breaking only one month in a year. The radio
instrument covers the
|
|
|
|
range
of 5,5 octave from 0.5 GHz to 18
GHz and it is unique in practice. On the Table 1, the to-day
|
|
|
|
and
future parameters of the RATAN-600 for solar observations are
presented. The most effective
|
|
|
|
regime
is a mode of usage 1/4 parts (Southern sector) of Main circular mirror
together with a Flat
|
|
|
|
periscope
mirror, consisting on 124 flat reflecting elements (8,5 m per 3 m) (see
Fig.2). This antenna
|
|
|
|
system
forms the diagram pattern in the form of a vertical knife. Inside Southern
sector there are
|
|
|
|
circular
rail-way tracts for moving of "Receive Mirror" (third mirror
together with a receive cabin) in
|
|
|
|
multi
azimuth regime and tracking. The radiation from the Sun struck to the Flat
mirror and is
|
|
|
|
reflected
as a plane wave to a Main circular mirror of Southern sector. The range of
azimuth angles is
|
|
|
about
$\pm 30 degree$, that it is enough for realization of azimuth observations
in a time interval
|
|
|
|
$\pm
3 hours$ from a central meridian. Mean time of the culmination is about
9-00 UT. The receive
|
|
|
|
horns
are in focus of "Receive Mirror". The"Receive Mirror"
and room for the receivers are located
|
|
|
|
on a
uniform platform, which can move in any azimuth with high accuracy. For solar study the
|
|
|
|
Panoramic
Analyzer of Spectrum (PAS) is used (Bogod et al., 1999).
