Research on the Interaction of the Lower Atmosphere with Electromagnetic Waves of Millimeter Wavelength through Line-of-Sight Propagation Studies.

Abstract

The report describes a continuing program of research in the propagation of millimeter waves over a 28-km line-of-sight path using sampling arrays of antennas. Experimentally, two frequencies (34.89 and 11.63 GHz) are used. Directly measured quantities are amplitude and relative phase at each of eight receiving antennas (on the higher frequency), as received from each of two transmitting antennas. The report describes the data-taking procedure, recent modifications made to the equipment, and various data-reduction techniques. Emphasis is on the small signal fluctuations arising from atmospheric turbulence. (Modified author abstract)
