Wideband Propagation Measurements in the Presence of Forests
Abstract
This report describes the conduct and provides representative analysis of the results of an experimental program designed to measure the transmission characteristics of UHF radio channels in a forested environment. The program described is the initial phase of what may become a much larger effort, and the emphasis here is to test the experimental procedures, equipment, and analysis technique for their appropriateness to the long-range objectives, and to gain some preliminary insight to the propagation parameters important for wideband and spread-spectrum systems. The test instrumentation used was a pseudo-noise channel probe with 300-MHz bandwidth. It provided a direct representation of the channel impulse response which then was recorded in both analog and digital formats. The analyses of these recordings now provide measures of overall path loss, multipath delay spreads, and derived spectral responses. (Author)
