Abstract

The invention discloses a performance measuring and on-line correcting device and method for an antenna housing. The device comprises a movement drive system, a positioning fixture, a reflecting surface mold, an ejection device, an electrical thickness testing system and a polishing system. The movement drive system is arranged on a bed body and used for controlling the movement and polishing of the antenna housing, and the movement drive system comprises a longitudinal translation part, a transverse translation part, a testing rotary table part and a rotating part. The positioning fixture and the reflecting surface mold are connected with a spindle of the movement drive system, one end of the positioning fixture clamps the antenna housing, the reflecting surface mold is arranged inside the antenna housing, and the outer shape surface of the reflecting surface mold is an outer shape equidistant offset face of the antenna housing. The ejection device abuts against the other end of the antenna housing. The electrical thickness testing system is used for transmitting, receiving and processing test microwave signals so that the electrical thickness of the antenna housing can be obtained. The polishing system is placed on the other side of the antenna housing and can grind and correct the outer shape surface of the antenna housing. By means of the performance measuring and on-line correcting device and method for the antenna housing, the defects that in an existing split type measuring and polishing mode, the repeated installation errors are large and the efficiency is low can be overcome, and the manufacturing accuracy of an existing antenna housing is greatly improved.

Description

technical field [0001] The invention particularly relates to a radome performance measurement and online correction device and method. Background technique [0002] The radome is a key component that integrates aerodynamic, structural and electrical performance. Its performance such as wave transmission rate and line-of-sight error will directly affect the missile's operating range, miss distance and stability, and its performance needs to be precisely controlled. In order to solve the performance out-of-poor caused by wall thickness processing errors and material dielectric property inhomogeneity in the manufacturing process, it is necessary to accurately measure the electrical properties of the radome, and analyze the areas and out-of-poor performance based on the test data. difference, for precise correction. [0003] The performance measurement and correction of the radome in the prior art are carried out on different devices, the performance measurement is carried out ...
