Abstract : An experimental study was made of errors contributed by the atmosphere in azimuth angle measurements made with short-baseline microwave systems. Time variations in the azimuth of a fixed target were found to decrease with increasing radio frequency in the range of 9.4 to 35 GHz. Ground multipath is indicated as the principal source of these variations which are characterized, especially at the lower frequencies, by long-term trends and lack of correlation on adjacent paths.
