Example Embodiment

A radar radome of the present invention comprises a truncated spherical cover body 1, and the ratio of the diameter of the truncated spherical cover body 1 to the diameter of the antenna installed inside is 1.6. The ratio of the diameter of the truncated spherical cap body to the diameter of the truncated spherical base circle is in the range of 1.24. The spherical cover body 1 is divided into several regular pentagons, regular hexagons and irregular polygons, which are in the form of two-dimensional random blocks and are arranged in a manner similar to the surface of a football. The entire spherical cover body 1 is assembled by 31 modules, the spherical part is assembled by regular pentagon and regular hexagon modules, and the spherical section is made of irregular polygon modules and regular pentagon and regular hexagon modules of the spherical part. assembled. Each of the modules constituting the truncated spherical cover body 1 is a honeycomb sandwich structure, that is, t...

Abstract

The invention discloses a radar antenna housing. In the radar antenna housing, a spherical segment housing body which has a honeycomb sandwich structure is adopted; the radar antenna housing is formed by splicing modules which are made of glass fiber reinforced plastic and paper honeycombs; thus the wave penetrating performance and the mechanical strength of the glass fiber reinforced plastic and the paper honeycombs are fully utilized, and the effects of sheltering rain, snow, hail, strong light and the like are achieved without the influence on the normal use of a radar antenna. In addition, a lightning rod is arranged beside the housing body, so the possibility of lightning stroke can be greatly reduced when the radar antenna housing is used on a tall building so as to fulfill the aim of safe use.

Description

technical field [0001] The invention relates to a radar antenna part or a device combined with a radar antenna, in particular to a radar radome which is not tightly mechanically coupled with a radiation unit. [0002] Background technique [0002] As a signal receiving device, the radar antenna generally needs to be placed in an open space or on the roof of a building. As a device for outdoor use, it is easily affected by the harsh external environment. For example: rain, snow, hail, strong sunlight, etc. will have a long-term impact on the radar antenna, affecting the radiation characteristics and circuit characteristics of the antenna, and affecting the use of the radar. At present, there have been radomes specially used to protect outdoor radar antennas. For example: Chinese patent CN2433738Y discloses a ground radar radome, by setting a truncated spherical cover to wrap the radar antenna, it can avoid being affected by rain, snow, hail and strong light. Since the ...
