Abstract:

Simultaneous transmission loss measurements were made at Ku-band 16 GHz and C-band 5 GHz on a 161 km tropospheric scatter link between Prospect Hill in Waltham, MA and Mt. Tug in Enfield, NH. The experiment was conducted to demonstrate the feasibility of using th higher frequency for scatter communication. Between April and September, 1987, two-frequency observations were obtained during a variety of weather conditions. Clear weather measurements were made to generate transmission loss estimates for comparison with tropospheric scatter model predictions. Observations during times with precipitation were made to assess the anticipated problems of an excess of transmission loss due to attenuation by rain at the higher frequency and an increase in delay spread due to scattering by rain.
