AI Technical Summary

Technical Problem

In order to meet the strength requirements, the large-span flat panel radome leads to poor radar wave transmission performance and low space utilization.

Method used

A large-span flat radome with foam support columns was designed. By setting foam support columns in the middle of the cover body and combining the structure of interlayer, inner skin and outer skin, the rigid strength and space utilization of the radome are improved.

Benefits of technology

The rigid strength of the radome is improved, collapse and shrinkage are reduced, the thickness of the cover and the distance between antenna elements are reduced, space utilization is improved, and radar wave transmission performance is improved.

Abstract

The invention provides a large-span planar antenna housing containing foam supporting columns and a manufacturing method thereof, and relates to the technical field of radar antennas. According to the antenna housing, the foam supporting column is additionally arranged in the middle of the housing body to serve as a supporting structure, the rigidity and strength of the antenna housing are improved, collapse and contraction of the antenna housing are reduced, the thickness of the housing body is reduced, the distance between the wall face of the antenna housing and an internal antenna unit is reduced, and therefore the overall section space is reduced, and the space utilization rate is improved.
