Abstract
This report describes the ground reflection characteristics of 42-GHz millimeter band signals for a wireless HDTV camera system. Under typical operating conditions ground reflections degrade the demodulated picture in the wireless HDTV camera system. In order to verify the operational availability of the wireless HDTV camera system, we measured the DU ratios of the multipath and the equivalent reflection coefficients in various environments and made a subjective assessment of HDTV picture quality. As a result, it has been found that the wireless HDTV camera system works adequately under any actual operating conditions with sharp antennas.
