Atmospheric water vapor calibrations: Radiometer technique
Abstract
A radiometric technique for determining atmospheric water vapor effects on radiometric range and Doppler has been partially evaluated. Empirical test results indicate that the microwave thermal emission from water vapor at 22.2 and 31.4 GHz frequencies can yield line-of-sight electrical phase path calibrations to the centimeter accuracy level.
