Antenna beamwidth and beamshape control techniques for satellite-borne synthetic aperture radar systems
Abstract
The paper discusses methods of beamwidth and beamshape control suitable for a satellite-borne synthetic aperture radar (SAR) sensor system. The results of a parametric analysis which relates satellite orbital attitude, depression angle, beam width, and swath width are summarized. Attention is given to beam shaping techniques and their application to aperture configurations of interest to generate desired radiation patterns. Baseline antenna performance characteristics are established for (1) a planar phased array and for (2) a reflector (optically fed) antenna configuration. Finally, hardware considerations, performance degradation effects, packaging, deployment, and refurlability are discussed.
