New configurations of interferometers ensuring
practically equal resolution in all beam cross-sections
are suggested. The suggestion is based on the arrangement of
elements along the hexagon perimeter (or partly inside it)
due to which a complete equidistant (regular) coverage of a
hexagonal domain in the 
-plane in the cross-correlation
regime is obtained. A comparison of the systems proposed with
a number of other ones showed that one can obtain the
prescribed resolution and field of view using a smaller number
of elements (antennas).
Key words: instrumentation: interferometers
