Abstract

The invention relates to the technical field of radome design and particularly relates to an equal-volume-ratio conformal mapping spherical radome, a plurality of periodic units are uniformly distributed on the spherical surface of the radome; the periodic units are not covered; the spherical crown area passing through the central point P of any periodic unit is in direct proportion to the circlearea of the mapping point Q passing through the central point P; the area of the spherical crown takes an axis passing through the sphere center of the radome and the vertex P0 of the radome as a central axis; the circle area takes the vertical mapping point Q0 of the vertex P0 of the antenna housing 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 spherical radome, a conformal absorber is established on the spherical surface, and electrical characteristics of the radome are satisfied.

Description

technical field [0001] The invention relates to the technical field of radome design, in particular to a spherical radome with conformal mapping of equal area ratio. Background technique [0002] The spherical membrane is fixed on an airtight platform with a pressure plate around the kerf, and the surrounding area is tensioned with ropes or fixed by other methods, and the interior is inflated. Its advantages are that the cover wall is thin and uniform, the electrical performance is good, and it is suitable for broadband work; the cover body is soft and easy to fold, light in weight, small in size, and convenient in transportation, storage and installation. [0003] 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 with cylindrical conformality due to the fact that cylindrical conformality bends in only one direction. When building conforma...
