A comparison of copolar and cochannel satellite interference prediction models with experimental results at 11.6 and 20 GHz

One of the main propagation effects on interference between adjacent Earth- space paths is the differential rain attenuation. In the present paper, two existing copolar and cochannel satellite interference prediction models ar e compared with experimental data of this kind, derived from radar or atten uation measurements. The comparison shows a quite satisfactory agreement an d this combined with the fact that the data refer to satellites quite displ aced in the geostationary orbit leads to the following conclusion: the pred ictive models under consideration can be used not only for fixed satellite systems but also for mobile systems using general antennas with low gains.
