Abstract:

In an effort to solve the fading problem encountered in large-aperture arrays of the Wullenweber type, several space-diversity antifading techniques are proposed and discussed. The results of an experimental study of dual-diversity systems incorporating these techniques are presented and the performance of these systems in relation to that of a conventional space diversity system of small-aperture elements is determined. Both the experimental method and the analysis techniques used in evaluating the performance of each diversity system are described in detail.
