SUMMARY 1
|
|
|
An
important characteristic of MWRH would be the simultaneous obtaining of the
|
|
|
spatial
spectrum at different wavelengths. Obtaining radio images of the solar
|
|
|
corona
during the daytime by recording all spatial scales is possible through the
|
|
|
implementation
of adaptive multiwave approach. The essence of the method is as
|
|
|
follows.
All SSRT antennas will be equipped with multiwave modules. The adaptive
|
|
|
multiwave
mode make sit possible to realize a redundancy of the SSRT antenna
|
|
|
array.
For calibrations and for observations of slowly varying structures, it is
|
|
|
intended
to obtain solar radio images consecutively at different wavelengths.
|
|
|
Specifically,
either all SSRT antennas or one and the same optimum configuration
|
|
|
will
be used for each wavelength. Thus it is intended to obtain a quality image
of all
|
|
|
Sun
at six frequencies. The only limitation will be the overlay of noon images
at
|
|
|
frequencies
higher than the SSRT design frequency, 5.7 GHz. This will be caused by
|
|
|
the
mismatch of the lowest spatial frequency to the angular size of the Sun for
these
|
|
|
frequencies.
The use of all SSRT antennas in synthesizing the image make sit
|
|
|
possible
to obtain a highest-quality image but increases substantially (several
times)
|
|
|
the
amount of information. Therefore, the selection of the particular
configuration in
|
|
this
case will be influenced not only by the physical expediency but also by the
|
|
|
overall
performance of the system.
