Optimal antenna area design for spaceborne SAR

Abstract

Three optimizations of the antenna area and power for the spaceborne synthetic aperture radar (SAR) are presented in this thesis. Since the antenna area and power are the major factors in performance and budget of the spaceborne SAR, a lot of attention should be paid on the determination of the antenna area and power for different applications and/or purposes. The proposed three optimizations decide the antenna area and power giving the optimal performances in the stripmap cost (defined as mass per swath width) sense for a specific incidence angle, in the spotlight cost (defined as mass per target area) sense for a specific incidence angle, and in the stripmap mapping area sense over a wide range of incidence angles, respectively.
