Abstract
A new radioheliograph has been constructed to explicate the mechanism of
solar flares. The
radioheliograph is an interferometer with T-shaped two-dimensional
antenna arrays. In order to
obtain high spatial and high time resolution simultaneously, element
antennas are allocated more
densely in the inner part of the T-shaped array and more sparsely in the
outer part. Correlations
with all antenna combinations are calculated by a multichannel 1-b
correlator. The design
principles and performances of the radioheliograph receivers are
described.
