Abstract :
This paper describes the analysis performed on a developmental ultra-high-frequency (UHF) antenna intended to support ultrawide synthetic aperture radar (SAR) on a Global Hawk platform. Both full-scale and ¼-scale test articles were fabricated. The patterns of the ¼-scale articles were measured over a full 4π steradians. Full-scale articles were measured over reduced angular regions sufficient to validate scaling. All measurements were fully polarimetric
