Abstract

The invention relates to a feed source distance measuring device. The feed source distance measuring device is used for a phased array antenna. The phased array antenna comprises an antenna array surface and a feed source arranged on at least one side of the antenna array surface, the feed source is provided with an inclined feed source opening surface, and the feed source distance measuring device comprises a bracket, array surface pasting blocks, a feed source opening surface pasting block, fixed length blocks and a measuring device, wherein the bracket is arranged on the side surface of theantenna array surface, the bracket comprises at least one measuring rod, and the measuring rods are provided with sliding grooves perpendicular to the working surface; the array surface pasting blocks movably arranged in the sliding grooves and is attached to a working surface; the feed source opening surface pasting block is lapped on the feed source, the feed source opening surface pasting block is provided with a measuring surface which is vertically arranged and coincides with the center of the feed source opening surface in the vertical direction; the fixed length blocks are movably arranged in the sliding grooves and attached to the measuring surface; and the measuring device is used for measuring the distance between the fixed length blocks and the array surface pasting blocks. According to the feed source distance measuring device, the horizontal distance measuring process from the center of the feed source opening surface to the antenna array surface is simple, the measuringefficiency is high, and the measuring success rate can reach 100 %.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a feed source distance measurement device and a feed source distance measurement method. Background technique [0002] Horn-fed two-way air-fed phased array antenna is mainly composed of phased array antenna front (hereinafter referred to as "antenna front") and two-way working feed horn (hereinafter referred to as "feed source"). The two feed sources are installed at a certain angle relative to the two sides of the antenna array. The horizontal distance from the center of the feed port to the antenna array has accuracy requirements. It is necessary to measure the horizontal distance from the center of the feed port on both sides to the antenna array. [0003] In the existing technology, the measurement schemes that meet the accuracy requirements are: Scheme 1, use a 1m height gauge for measurement, place the height gauge horizontally and measure the height gauge base close ...
