Radar dome unit piece and manufacturing process, connecting method and dividing method thereof

Abstract

The present invention provides a unicell for radar dome with waterproof resin glue covering and glass epoxy layer outer layer, glass epoxy layer as inner layer ,while froth core layer located between the inner layer and outer layer. Seam structure of peripheral of the unicell is plane overlapping edge with solid glass steel layer integrately formed with the unicell, in which stainless steel screw cap is preburied in the upper overlapping edge, and attachment hole is opened in the lower overlapping edge. The present invention further provides manufacturing technique, attaching method and partiting method for unicell. The present invention realizes blocking method without parallel for adjacent edge, improves electrical property of radom, and enhances overall strength of radom, also improves wind resistance ability and leak resistance ability.

Description

Technical field [0001] The invention relates to a radar radome capable of eliminating the influence of the environment on a radar antenna, in particular to a radar radome unit made of glass fiber reinforced plastic and its manufacturing process, connection method and division method. Background technique [0002] The ground radar radome can eliminate the influence of the environment on the radar antenna, so that the radar antenna can work normally in complex and harsh weather. Large radome is generally made of materials with high electromagnetic transparency, and its shape is truncated spherical, with a diameter ranging from a few meters to more than 20 meters. In order to facilitate transportation and installation, it is generally assembled from several small units. Due to the special working conditions of the radome, the requirements for its electrical performance, weather resistance and structural strength are relatively strict. The structure of each unit of the radome,...

AI Technical Summary

Problems solved by technology

This kind of unit and its manufacturing process and connection method have poor appearance quality and high production cost. It is required to build a full house of scaffolding inside and outside the radome, and it needs to be drilled on site. The construction efficiency is low, which affects the radome. Structural strength; the current segmentation method, the size of the unit elements is different, the specifications are many, and the adjacent sides are parallel to each other, which will increase the sidelobe of the received waveform, increase the transmission loss, and affect the electrical performance of the antenna
