Abstract

The present invention relates to the technical field of radome design, in particular to a spherical radome with conformal mapping of the equal diameter ratio. A plurality of periodic units are evenly distributed on the spherical surface of the radome; there is no coverage between each periodic unit; Center point P to radome vertex P 0 The arc length of the center point P and the mapping point Q to the radome vertex P 0 The vertical mapping point Q 0 Proportional to the distance; the mapping point Q of the center point P and the radome vertex P 0 The vertical mapping point Q 0 Located on the same horizontal plane; the plane with the mapping point Q as the origin and the tangent plane T with the center point P as the origin P have a local mapping relationship. The invention realizes the establishment of the conformal absorber on the spherical surface and satisfies 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 conformal mapping of the equal-diameter ratio. 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 plana...
