Embodiment Construction

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0020] Such as figure 1 , 2 As shown in and 3 , the radome described in the embodiment of the present invention is covered on the radar with the reflector antenna, the radome includes a cone-shaped cover body 1 , and the radar includes the reflector antenna 2 .

[0021] The diameter of the bottom surface of the truncated conical cover 1 is d, wherein d is the diameter of the reflective surface of the reflector antenna 2; the height of the truncated conical cover 1 is 1.005*h+(6c / f), wherein the premultiplied coefficient is 1.005 In order to compensate for the possible impact of manufacturing tolerances and measurement errors, 0.5% of the height margin is added. h is the height of the antenna physical mechanism of t...

Abstract

The present invention relates to an antenna cover used for a reflector antenna and a manufacturing method thereof. The antenna cover comprises a truncated cone shaped cover body, and the diameter of a lower bottom surface of the truncated cone shaped cover body is d, wherein d is the actinal surface diameter of a reflector of the reflector antenna. The height of the truncated cone shaped cover body is 1.05*h+(6c / f), wherein h is the antenna physical mechanism height of the reflector antenna, f is the working frequency of the reflector antenna, and c is the vacuum light speed. The diameter of an upper bottom surface of the truncated cone shaped cover body is d-2*a*tan(w / 2), wherein a is the reflector focal length of the reflector antenna, and w is a reflector field angle of the reflector antenna. The antenna cover provided by the present invention can cover the antenna, at the same time, enables the weight, size and wind resistance of the cover body to be reduced and the total weight and size of a radar to be reduced overall, and is convenient to transport and erect.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a radome for a reflector antenna and a manufacturing method thereof. Background technique [0002] For rain radar and millimeter-wave cloud radar used outdoors, the reflector antenna is directly exposed to the natural environment. When encountering rainfall and snowfall, the accumulation of water and snow in the antenna reflector will cause the antenna loss to increase and the gain to decrease, seriously Affect the radar detection effect, so a radome must be added. The radome protects the antenna and realizes the function of wave penetration. Traditionally, outdoor radars can use two radome methods. [0003] A radome adopts a truncated spherical structure, and the antenna, the entire servo structure and even the radar transceiver components are all covered in the truncated spherical hood. This type of radome has problems such as large volume and weight of the radome, high proc...
