Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0013] The invention relates to a two-dimensional phase scanning technology, which can perform beam scanning of 360° horizontally and -30-30° vertically, accurately point the beam to other communication members, and simultaneously support high-speed data distribution and sum-difference beam angle measurement functions.

[0014] The antenna scheme adopts the form of a cylindrical array antenna. The cylindrical array consists of 96 radiating columns to form a cylinder, and each array contains 8 radiating elements and 8 phase shifters to realize beam scanning in the elevation plane. The 96 radial columns divide the cylindrical array into 96 equal parts on the azimuth plane, and each array is equivalent to an angle of 3.75° on the azimuth plane. Each radiating column has a T co...

Abstract

The invention provides a cylindrical integrated active phased-array antenna. 96 linear radiation arrays are arranged in parallel to form a cylindrical array phase, each linear radiation array includes 8 radiation units and 8 phase shifters, and wave beam scanning in the pitching surface is realized; and each radiation column is connected with a switch array via a T/R assembly, the switch array divides the 96 linear radiation arrays into four groups, and a power amplifier is connected via an circulator. According to the invention, an independent antenna can be used to realize omnidirectional scanning with neither increase of array planes nor addition of mechanical scanning, the complexity and power consumption of an antenna system are reduced, and problems in heat radiation and the like are solved.

Description

technical field [0001] The invention belongs to the application field of antenna technology and relates to a phased array antenna. Background technique [0002] The phased array antenna has the ability of beam pointing and beam forming to change rapidly, it is easy to form multiple beams, and it can realize signal power combination in space, so that the phased array radar can complete multiple functions. Compared with the mechanical scanning antenna system, the active phased array antenna system has the advantages of fast scanning and flexible beam control. It is easy to realize spatial orientation and filtering and multi-beam functions, which meets the increasingly high requirements of modern radar and communication technology. So as to be widely used. [0003] Traditional phased array antennas such as figure 1 As shown, each antenna unit is connected to a T / R component, and connected to the circulator, receiver and wave control system through the feed network. During th...
