    摘要: A telescope has an entrance pupil region; a first concave mirror (M1) belonging to a first rotationally symmetric aspheric surface and reflecting light passing through the entrance pupil region; a second convex mirror (M2) belonging to a second rotationally symmetric aspheric surface and reflecting light reflected by the first mirror; a third convex mirror (M3) belonging to a third rotationally symmetric aspheric surface and reflecting light reflected by the second mirror; a fourth concave mirror belonging to a fourth rotationally symmetric aspheric surface and reflecting light reflected by the second mirror to an exit pupil. The first, second, third and fourth rotationally symmetric aspheric surfaces are centered on the symmetry axis of the third mirror. The first, second and fourth mirrors are centered along the first direction perpendicular to the optical axis and off-centered in a second direction perpendicular to the symmetry axis and to the first direction.

    摘要: A real time SAR processing system for processing synthetic aperture radar (SAR) return signals and a method for real time processing of SAR return signals. The real time SAR processing system for processing synthetic aperture radar return signals comprises a light source (1) for generating a coherent, plane electromagnetic wave; light modulation means (2) for modulating the incident wave according to the radar return signals and outputting a modulated wave; and optical processing means (3) for submitting the modulated wave to an optical signal processing for radar image reconstruction. The light modulation means (2) comprises a plurality of addressable pixels (30) which are controlled based on the radar return signals. Light detection means (4) for detecting the processed wave and generating a corresponding electrical radar image signal are provided.
