Abstract : The effects of atmospheric irregularities on line-of-sight propagation are studied both experimentally and theoretically. The experimental measurements utilize a pair of 35 GHz transmitting antennas, time shared through a rapid switching arrangement, and an array of receiving antennas at each of which amplitude and relative phase of the arriving wave are measured separately. This configuration is coordinated with 11 GHz transmissions propagated over the same 28 km path. The entire set-up is highly versatile and permits a variety of different types of propagation measurements to be made in near simultaneity. (Author)
