Includes bibliographical references (page 7). "In 1984 a microwave propagation experiment was conducted in Alert, NWT, to study the characteristics of low angle fading at a frequency of 38 GHz. By monitoring the CW signal transmitted from the orbiting LES-8 satellite, propagation data were gathered over a range of elevation angles from 1 to 21 degrees. A total of three sets of measurements were made in the spring, summer and winter. These allowed comparisons to be made of the seasonal characteristics of low angle fading in the arctic. The experimental data are examined with respect to the atmospheric conditions observed at Alert. Other results presented in this report include the variation of the median signal level with the elevation angle, cumulative distributions of the received signal level and fade rate statistics. The amount of signal fading increased rapidly as the elevation angle decreased. Fading was most severe in the summer which also had the highest fade rates. Very little fading was observed in winter"--Abstract, page 1. Issued also in print format. Radio Transmitters and transmission Fading Canada, Northern. Radio wave propagation Canada, Northern.
