Investigation of Millimeter Wave Propagation in the Atmosphere.
Abstract
This report documents the results of five years of research conducted on the propagation of millimeter waves through the atmospheric surface layer. At a site in Flatville, Illinois, radiation in the frequency range from 116 GHz to 230 GHz was propagated along at 1/4 km horizontal path instrumented with multiple meteorological sensors to characterize the state of the atmosphere. The millimeter wave beam propagated at a height of 3.7m to a receiver van that had four receiver antennas spaced in a non-redundant manner to allow measurements of amplitude, phase difference and mutual coherence at spacings from 1.43m to 10m. Comparisons between the clear air propagation data and theory showed close agreement. (Author)
