<p>PROBLEM TO BE SOLVED: To solve such a problem of conventional radar that, although first active phased array antennas for radar and second active phased array antennas for ECM/ESM are arranged on the same aperture, the diameter of antenna aperture is increased because they are arranged in block, respectively. SOLUTION: A thinning arrangement of first active phased array antennas 1 is determined such that they are arranged along a desired aperture distribution from an antenna aperture having a plurality of element antenna coordinates. Circularly polarized wave element antennas 2 constituting a second active phased array are arranged at all element antenna coordinates except the thinning arrangement of first active phased array antennas 1.</p> |
