Abstract
Measurement of Cross-Polarization Imbalance (CPI) of the phased array antenna is a critical step during SAR payload characterization. In this paper, we demonstrate a time-efficient measurement scheme of H-V CPI for EOS-04 antenna via single 2-D raster-scan near-field measurements. The set-up utilizes full-polarization mode of EOS-04 payload and a dual polarized probe for this purpose.
