Quadruple-site radiometric diversity measurements at 11.6 GHz
Abstract
Results from a quadruple-site radiometric diversity experiment at 11.6 GHz are presented. Data cover 1 yr of continuous measurements. Considerable diversity gain is observed for dual-site pairs. The use of more than two sites increases diversity gain only negligibly. Caused by specific local weather mechanisms, no consistent dependency of diversity gain on site and path-separation is observed. Extrapolation to 20 and 30 GHz, based on relationships obtained from multifrequency radiometer measurements in the same area, confirms the importance of site diversity application at these and higher frequencies.
