UHF Radiowave Propagation through Forests

Abstract

Using the US Army's Wideband Propagation Measurement System, radio wave propagation experiments were twice conducted in Coventry, Connecticut - first in August 1987 and again in November 1987 after the autumnal leaf fall. A selected subset of these data, representing nearly one-hundred experiments conducted over different distances with different frequencies, polarizations and antenna heights, has been analyzed and trends established which relate delay spread to the environmental and radiophysical parameters characterizing the propagation path. Keywords: UHF Radiowave propagation, Forest, Foliage, Vegetation, Trees, Channel characterization, Transmission Loss, Delay spread.
