A real-time distributed architecture for a multichannel millimeter-wave radiometer system is described. The system consists of four microwave radiometer subsystems which provide a total of nine frequency channels, a steerable reflector to permit slant-path measurements, and a host computer for recording and evaluating the data. The nine channels span the water vapor and oxygen absorption lines in the 20-to-60-GHz range, with the lowest frequencies (20.6, 22.235 and 31.65 GHz) to be used for water vapor and liquid water retrievals and the six highest frequencies (50.3, 52.85, 53.85, 55.45, 58.8 and 61.15 GHz) to be used for temperature profile retrievals. The radiometer has a zenith-angle-scanning capability for the purpose of both calibration and the study of temporal/spatial variations in atmospheric water vapor and temperature.
