FIELD: antennas.SUBSTANCE: invention relates to antennas of superhigh frequencies. Peculiar feature of claimed waveguide slotted antenna arrays is that in general scheme of waveguide slotted antenna array in vertical plane, phase distribution is calculated by enumerative searching for cross-polarization radiation, based on minimum criterion of maximum level of cross-polarization petals, that is performed by decomposition of counter-phase waveguide lines, turning waveguide-coaxial transitions at 180°, or is introduced into phase scanning beam on main polarization, in presence of phase changers in antenna circuit.EFFECT: technical result is higher noise immunity of radar station.3 cl, 2 dwg |
