    • A novel method for calculating the surface shapes for subreflectors in a suboptic assembly of a tri-reflector spherical antenna system is introduced, modeled from a generalization of Galindo-Israel's method of solving partial differential equations to correct for spherical aberration and provide uniform feed to aperture mapping. In a first embodiment, the suboptic assembly moves as a single unit to achieve scan while the main reflector remains stationary. A feed horn is tilted during scan to maintain the illuminated area on the main spherical reflector fixed throughout the scan thereby eliminating the need to oversize the main spherical reflector. In an alternate embodiment, both the main spherical reflector and the suboptic assembly are fixed. A flat mirror is used to create a virtual image of the suboptic assembly. Scan is achieved by rotating the mirror about the spherical center of the main reflector. The feed horn is tilted during scan to maintain the illuminated area on the main spherical reflector fixed throughout the scan.
    • 引入了一种用于计算三反射器球面天线系统的次反射组件中的次反射器的表面形状的新颖方法,其由Galindo-Israel的解决偏微分方程的方法的一般化来校正球面像差,并提供均匀的进给孔 映射。 在第一实施例中,次主组件作为单个单元移动以实现扫描,而主反射器保持静止。 在扫描期间,馈电喇叭倾斜以保持主球面反射器上的照明区域在整个扫描中固定,从而不需要使主球面反射器过大。 在替代实施例中,主球形反射器和次级组件都是固定的。 平面镜用于创建次要装配体的虚拟镜像。 通过围绕主反射体的球面中心旋转镜子来实现扫描。 馈电喇叭在扫描期间倾斜,以保持主球面反射器上的照明区域在整个扫描中固定。
