Abstract

The invention discloses a universal reconfigurable phased-array antenna test truss. The truss comprises a support frame, a pitching adjusting mechanism and a truss structure. The truss structure comprises a plurality of trusses and a plurality of antenna fixing mechanisms. Horizontal sliding grooves which are vertically spaced and parallel are formed in the side face of the truss. Every two adjacent trusses are fixedly connected through a quick disassembly assembly, so that the horizontal sliding grooves of every two adjacent trusses are connected. Each antenna fixing mechanism is vertically arranged between the two corresponding horizontal sliding grooves, the end portions of the antenna fixing mechanisms are connected with the horizontal sliding grooves in a sliding mode, the lower endsof the trusses are hinged to the supporting frame, the two ends of the pitching adjusting mechanism are connected with the trusses and the supporting frame respectively, and the pitching adjusting mechanism can drive the truss structure to rotate relative to the supporting frame. The test truss can be suitable for testing various types of phased-array antennas.

Description

technical field

[0001] The invention relates to the technical field of antenna testing, in particular to a universal reconfigurable phased array antenna testing truss. Background technique

[0002] Phased array antennas are widely used in communication, meteorology, electronic countermeasures, radar and navigation and other fields. The antenna front of the phased array antenna is composed of many radiating and receiving units. The number of units is related to the performance of the radar. It can range from several to several thousand. These units are regularly arranged on the plane to form an array antenna. Each The units are fed with currents of different phases, thereby radiating beams with different directions in space. According to the unit distribution, it can be divided into linear array and area array. The most commonly used linear array is the linear array in which the centers of each unit are arranged on a straight line at equal intervals, and there are also multi...
