Abstract

The invention relates to an array antenna and a wave beam pointing control method thereof, and relates to a mechanical type phase control scanning array antennae and the wave beam pointing control method thereof. The mechanical type phase control scanning array antennae comprises an antenna array formed by N circularly polarized antenna units, a power divider network and a coaxial line, wherein each circularly polarized antenna unit is arranged on rotating equipment; and the angle posture of each circularly polarized antenna and the phase configuration corresponding to the different angle postures of each circularly polarized antenna unit are subjected to the rotary control of the rotating equipment, so that the wave beam pointing of the antenna array can be contorlled, and furhter a phase control wave beam scanning function is realized. The mechanical type phase control scanning array antennae realizes the phase-controlled wave beam scanning on the basis of setting of the initial phase position information carried by the self angle postures of the circularly polarized antenna units, and the phase position deployment of the antenna array; and the phase control wave beam scanning of the antenna array can be realized by the design, the operation mode is simple and flexible, and the mechanical type phase control scanning array antennae and the wave beam pointing control method thereof can adapt to multiple application occasions.

Description

technical field [0001] The invention relates to an array antenna and its beam pointing control method, in particular to a mechanical phased scanning array antenna and its beam pointing control method. Background technique [0002] The mechanical phased scanning array antenna is a kind of phase configuration of the entire array by means of mechanically controlling the angular attitude of the circularly polarized antenna unit and using the initial phase information contained in its own attitude.
