Measurements and predictions of multipath dispersion for troposcatter links
Abstract
Multipath dispersion measurements made on several 4.5 GHz paths in the United Kingdom are presented. Beamwidth and scatter angle dependence and several features of dispersion in angle and space diversity are discussed. These measurements and other from the literature are compared with predictions of dispersion. The predictions considerably underestimated the measured dispersion, but the inclusion of a beam broadening factor in the calculations gave a significant improvement in accuracy.
