Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0033] The invention relates to a high cross polarization isolated single-reflection surface compact field device, the compact field is mainly composed of a reflection surface of the single-reflection surface compact field, a feed source, a polarization grid, a feed source polarization state controller, a polarization grid Polarization state controller. The feed irradiates a precision rotating paraboloid with a single reflector compact field, and collimates the spherical wavefront into a plane wave. A polarization grid is arranged in front of the plane wave quiet zone of the single-reflector compact field, and polarization filtering or gating is performed on the quiet zone field, wherein the polarization states of the feed source and the polarization grid are controlled by respective controllers. The single reflector compact field device of th...
