To do this, it is necessary to
equip the SSRT antenna elements with multiwave
|
|
|
convertor
modules (MCM). Each MCM will comprise the polarization switch, the
|
|
|
low-noise
amplifier, the frequency converter with the synthesizer as the heterodyne,
|
|
|
the
attenuator, the phase shifter, and the microprocessor. It is admissible to
use six
|
|
|
wavelengths
in the frequency range from 2 GHz
to 10 GHz (2340, 3100, 4340,
|
|
|
5730,
7815 and 0300 MHz). MCM converts
signals of all waves received by the
|
|
|
antenna,
to an intermediate frequency. Synthesizers at all antennas are synchronized
|
|
|
by
the phase-stable reference signal. Signals at the intermediate frequency
are fed to
|
|
|
the
working room for a correlation processing.

An important characteristic of MWRH
would be the simultaneous obtaining of the
|
|
|
spatial
spectrum at different wavelengths. To accomplish this, it is possible to
use the
|
|
|
redundancy
of the SSRT antenna system. Based on the objective of flare
|
|
|
and
coronal mass ejection observation, the changes in spatial structures of our
interest
|
|
are
occurring in the region of high spatial frequencies. To record them
|
|
|
simultaneously,
it is sufficient to fill the edges of the SSRT array with antennas
|
|
|
operating
at different frequencies (Fig. 6). For measuring coronal magnetic fields,
the
|
|
|
instrument
will operate in the mode of sequential use of working wavelengths
|
|
|
(100...500
ms for each of the six working wavelengths). For observing a quiet Sun,
|
|
|
active
regions, filaments, and coronal holes, use will be made of the redundancy
of
|
|
|
the
SSRT antenna system to simultaneously obtaining spatial spectra at
different
|
|
|
wavelengths.
Thus we expect to obtain a flexible instrument for performing different
|
|
|
tasks
simultaneously.
