Abstract

The invention relates to the technical field of radome design and particularly relates to an equal-cycle-ratio conformal mapping spherical radome. The radome is characterized in that a plurality of periodic units are uniformly distributed on the spherical surface of the radome, wherein the periodic units are not covered; the first circumference passing through the central point P of any periodic unit is in direct proportion to the second circumference passing through the mapping point Q of the central point P; the first circumference takes an axis passing through the sphere center of the radome and the vertex P0 of the radome as a central axis; the second circumference takes the vertical mapping point Q0 of the vertex P0 of the radome as the center of a circle; the mapping point Q of the central point P and the vertical mapping point Q0 of the antenna housing vertex P0 are positioned on the same horizontal plane; a plane taking the mapping point Q as an original point and a tangent plane TP taking the central point P as an original point have a local mapping relationship. According to the radome, a conformal absorber can be established on a spherical surface under the condition ofmeeting the electrical characteristics of the radome.

Description

technical field [0001] The invention relates to the technical field of radome design, in particular to a spherical radome with equiperipheral ratio conformal mapping. Background technique [0002] The spherical film of the spherical radome is fixed on the airtight platform with a pressure plate around the cutout. It has the advantages of thin and uniform cover wall, good electrical performance, and is suitable for broadband work; the cover body is soft and easy to fold, and light in weight , Small size, convenient transportation, storage and installation. The use of absorbing material on the surface of a spherical radome requires the creation of a conformal absorber on the spherical surface. Most conformal absorbing materials are studied in terms of cylindrical conformality, which is due to the fact that cylindrical conformality bends in only one direction. When building conformal absorbers on spherical surfaces, there is no suitable isometric mapping to place planar eleme...
