Results of a 12 GHz radiometric experiment in Hong Kong
Abstract
At frequencies above 10 GHz, rain attenuation can be a significant factor in determining the operating margins of communications satellite systems, particularly for links to tropical regions. To help establish accurate prediction models for those regions, data are presented from a one-year experiment in Hong Kong which measured sky noise at 11.6 GHz and rainfall rate. The measured and predicted rainfall rates were found to agree reasonably well, but the deduced path attenuation did not agree with the CCIR model. The results suggest that the present CCIR model overpredicts in the region of measurement.
