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 U,V-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).
