Abstract: A radiating phase-shifting cell is designed to favour the excitation of an equivalent resonance of the “slot” type in a first part of the phase cycle, and to favour an equivalent resonance of the “microstrip” type in a second part of the phase cycle. This property notably allows the bandwidth of the phase-shifting cells to be optimized. A phase range of 360° can in effect be segmented into two sub-ranges of around 180°. This segmentation into two sub-ranges is made possible by the complementarity of the resonant modes of the slot or microstrip type. The radiating phase-shifting cell is notably applicable to reflector arrays for an antenna designed to be installed on a space craft such as a telecommunications satellite or on a terrestrial terminal for satellite telecommunications or broadcasting systems.

Abstract: Embodiments described herein simplify the recognition of objects in synthetic aperture radar (SAR) imagery. This may be achieved by processing the image in order to make the shadow caused by the object appear more similar to the object. Alternatively, this may be achieved by processing the image in order to make the layover caused by the object appear more similar to the object. Manipulation of the shadow caused by the object and the layover caused by the object may comprise altering the aspect ratio of the image, and in the case of manipulating the shadow caused by the image, may further comprise transforming the image by reflection or rotation. The aspect ratio of the image may be altered based on information about the image collection geometry, obtained by the SAR.
