Background

Radomes are structures that protect the antenna system from the external environment. Outdoor antennas are usually placed in open air for work and are directly affected by storm, ice and snow, sand dust, solar radiation and the like in the natural world, so that the accuracy of the antennas is reduced, the service life is shortened and the working reliability is poor, and therefore, the antenna housing is required to be protected. However, the radome is an obstacle in front of the antenna, and absorbs and reflects the radiated wave of the antenna, changing the free space energy distribution of the antenna, and affecting the electrical performance of the antenna to some extent, especially the reflection of the radome wall and the diffraction of the uneven portion may cause the electric axis of the main lobe of the antenna to deviate, thereby generating aiming errors. Therefore, in the related art, inspection is usually performed by means of laser outer diameter runout detection after the radome is produced, so as to ensure the yield.
