Abstract

The invention relates to the technical field of radome design, in particular to a spherical radome of equal area ratio conformal mapping, wherein a plurality of periodic units are evenly distributed on the spherical surface of the radome; there is no coverage between the periodic units; The spherical crown area of ​​the center point P is proportional to the area of ​​the circle passing through the mapping point Q of the center point P; 0 The axis of the radome is the central axis; the area of ​​the circle is the vertex P of the radome 0 The vertical mapping point Q of 0 is the center of the circle; the mapping point Q of the center point P and the radome vertex P 0 The vertical mapping point Q of 0 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 Has a local mapping relationship. The present invention realizes the establishment of a conformal absorber on a 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 equal area ratio. Background technique [0002] The spherical film 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 in terms of cylindrical conformality, which is due to the fact that cylindrical conformality bends in only one direction. When buil...
