Abstract
The GEOSAT follow-on (GFO) WVR provides correction factors to the GFO altimeter range measurements for path delays due to water vapor. Radiometric 'brightness temperatures' of 22.2 and 37.0 GHz are measured with a shared antenna that has pattern footprints that overlap the altimeter footprint. The antenna is a 1.1 m diameter off-set parabolic reflector with a corrugated tri-band feed. Main beam efficiency is 94% and near beam (plus or minus 10 degrees) efficiency is 97%. This total power radiometer system has fully redundant electronics, weighs 12.7 kg and consumes 18 watts. Channel sensitivities are less than 0.18 degrees Kelvin for a 1 sec sample period.
