FIELD: antenna equipment.
SUBSTANCE: invention relates to superhigh-frequency equipment, specifically to antenna arrays (AA) used in onboard radar systems of ground-to-air missiles, air-to-air and other types of rockets and aircrafts (AC) located directly on conical or generalized conic surface of missile or aircraft nose part. Implementation of the proposed method of constructing a conic AA consists in solving a diffraction problem on the drop of an arbitrarily polarized plane wave on the cone conducting surface along its longitudinal axis, determining the electric current at an arbitrary point P on the surface of the cone, determining amplitude-phase and polarization excitation of emitters , which satisfies condition , where c is some arbitrary constant; "*" is a sign of complex conjugation and realization by means of slot (or other type) radiators of calculated amplitude-phase and polarization excitation.
EFFECT: technical result consists in formation of total-difference directive patterns in the direction of the axis of the cone with the maximum antenna directive gain on the total channel due to establishment of the optimum amplitude-phase and polarization excitation of the emitters, wherein the directional characteristics of antenna directive gain significantly exceed similar characteristics of the equivalent flat antenna and provide a level of cross-polarization radiation is substantially lower than the level of cross polarization in known analogues of conical AA and AA with ogival shape of surface.
